Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and more specifically, to a method for manufacturing a glass curtain wall with power generation function. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy has become a focus of attention across various industries. As an important component of modern buildings, aerospace aircraft windows, vehicle canopies, and ship window walls, glass curtain walls not only need to meet basic functions such as lighting, aesthetics, and structural safety, but are also gradually developing towards intelligence and multi-functionality; therefore, developing a glass curtain wall with power generation capabilities is of great significance.

[0003] Currently, glass curtain walls in related technologies mainly include glass sheets, surface stress layers, insulated layers, coating layers, and interlayer films. The glass sheet, as the substrate material, provides light transmission, mechanical support, and basic barrier functions. The surface stress layer forms compressive stress on the glass surface through physical tempering, significantly improving the glass's bending strength and impact resistance, and causing it to break into passivated small particles, reducing the risk of injury. The insulated layer reduces heat conduction and noise transmission, improving thermal insulation performance. The coating layer uses processes such as magnetron sputtering to deposit multiple thin films on the glass surface to control infrared and ultraviolet radiation from sunlight, improving indoor or cabin thermal comfort. The interlayer film is used in laminated glass to bond two or more panes of glass together, improving penetration resistance and sound insulation performance, and adhering the glass fragments to the film after breakage, preventing them from flying and causing injury.

[0004] However, in actual use, it still has some drawbacks, such as poor light transmittance. Traditional glass curtain walls often use high-reflection coatings or colored glass to adjust shading, resulting in visible light transmittance generally being less than 40%, which seriously affects the lighting and view inside the cabin; insufficient weather resistance. Traditional laminated glass uses PVB or EVA films, which are prone to moisture absorption and hydrolysis. Moreover, the coating power generation layer lacks inert gas protection. Under salt spray, high humidity and strong ultraviolet environment, the adhesive layer will bubble and the film layer will oxidize, resulting in serious power attenuation; and no power generation capability. Traditional curtain walls only serve the functions of structural enclosure and light transmission. They are energy-consuming units rather than energy-generating units and need to rely on external power supply systems. Summary of the Invention

[0005] To improve the above-mentioned problems and reduce the issues of poor light transmittance, insufficient weather resistance, and lack of power generation capacity in related technologies, this invention provides a method for manufacturing a glass curtain wall with power generation function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A method for manufacturing a glass curtain wall with power generation function includes the following steps: A1. In an environment with a temperature of 20℃ and a relative humidity of 50%, the modified glass substrate, the light conversion functional film, and the second modified glass substrate are stacked and aligned in the order of light-facing side, functional layer, and backlight side, and fed into a vacuum pre-compression laminating machine. Under normal temperature and vacuum degree ≤100Pa conditions, the laminating machine is pre-compressed for 4 minutes to obtain a pre-laminated semi-finished product. The pre-laminated semi-finished product is then fed into an autoclave, and the vacuum degree inside the autoclave is evacuated to ≤5kPa and maintained for 10 minutes. The temperature is increased to 120℃ at a heating rate of 2℃ / min, and nitrogen is simultaneously introduced to increase the pressure to 0.5MPa. The temperature and pressure are maintained at constant temperature and pressure for 30 minutes. The temperature is then increased to 140℃ at a heating rate of 2℃ / min and the pressure is increased to 1.2MPa. The temperature and pressure are maintained at constant temperature and pressure for 60 minutes. The temperature is then decreased to below 60℃ at a rate of 1.5℃ / min to release the pressure and remove the laminated glass sheet from the autoclave to obtain the tempered laminated glass sheet. A2. Trim and clean the excess adhesive film from the edges of the tempered laminated glass obtained in A1. Polish the edges of the glass. Attach perovskite thin-film photovoltaic strips to the back surface of the second modified glass substrate using optically transparent adhesive. Connect multiple photovoltaic strips in parallel groups followed by series connections. Weld 0.2mm thick tin-plated copper foil electrode leads to both ends of the series circuit, with an exposed length of 15-20mm. Apply a 0.5mm thick butyl rubber insulating layer to the base of the electrode leads and allow it to cure at room temperature for 2 hours. Apply a 6mm wide butyl rubber inner sealing layer to the circumferential edges of the laminated glass and an 8mm wide neutral silicone weather-resistant adhesive outer sealing layer. Cure at 25℃ and 50% relative humidity for 24 hours. Then assemble the aluminum alloy subframe and matching photovoltaic junction box to obtain a glass curtain wall with power generation capabilities.

After centrifugation and purification, the mixture was vacuum dried to obtain modified light-converting quantum dots. C2. PVB matrix resin, modified light-conversion quantum dots obtained in C1, polymeric dispersant, and ultraviolet absorber are put into a high-speed mixer and mixed at 1200 r / min for 15 min to obtain a mixture.

After cutting the float glass sheet with a thickness of 3-12mm to the required length using a CNC cutting machine and grinding and chamfering using a double-sided edge grinding machine, the sheet is cleaned by high-pressure spraying with deionized water, dried by hot air circulation, and then etched in a grid pattern on the bonding surface of the glass substrate using a 355nm ultraviolet laser. After etching, the sheet is ultrasonically cleaned with anhydrous ethanol for 5 minutes and dried at 80℃ for 30 minutes to obtain a glass preform with a microstructure. B2. The microstructured glass preform obtained in B1 is fed into a roller tempering furnace and heated to 620-680℃ at a heating rate of 15-25℃ / min, held for 40-130s, and then rapidly quenched to room temperature with compressed air at a pressure of 8-15KPa to obtain a tempered glass substrate. A silica antireflective film is prepared by curing silica sol on the light-facing surface of the first tempered glass substrate using a Czochralski method at a lifting speed of 2mm / s and a temperature of 110℃, and cured for a total of 30min. An offline magnetron sputtering process is then used at a vacuum level...

It is then absorbed by the perovskite thin-film photovoltaic strips on the back side to generate electricity. This gives the curtain wall the power generation function without affecting the light transmittance, thus enabling it to generate electricity. Detailed Implementation

Then, an AAA-grade solar simulator was used to measure the power generation under AM1.5 standard spectrum and irradiance of 1000 ppm. The current-voltage characteristic curves were tested at a battery temperature of 25℃ to calculate the photoelectric conversion efficiency, thereby characterizing the weather resistance of the glass curtain wall with power generation function. The test results and evaluation criteria are as follows: Photoelectric conversion efficiency > 5% (considered good electrical performance); Photoelectric conversion efficiency <5% (considered as poor electrical performance).

[0031] It should be specifically noted that the glass curtain wall with power generation function obtained above is the glass curtain wall with power generation function produced in a normal production process. The data of the glass curtain wall with power generation function that is defective in production shall be discarded. Examples 1-5

[0032] The table below shows the corresponding relationships between the preparation methods used for a glass curtain wall with power generation function.

The average value of the test results is recorded in the table below.

[0034] Table: Performance test results of light transmittance, electro-conversion efficiency retention rate, and photoelectric conversion efficiency in Examples 1-5 As can be seen from the table above, the preparation processes of the power-generating glass curtain walls in Examples 1-5 all effectively improve the production efficiency of glass curtain walls with power-generating functions. Ultra-white float glass, as the load-bearing substrate of the curtain wall, reduces the intrinsic absorption of visible light due to its low-iron properties. Laser etching forms a uniform micro-grid structure on the glass bonding surface, providing mechanical anchoring points for the adhesive film. Tempering treatment forms a continuous compressive stress layer on the glass surface, significantly improving mechanical strength and impact resistance. The nano-silica anti-reflective film reduces reflection loss on the glass surface through optical interference, improving the utilization rate of full-spectrum incident light. The heat-resistant double-silver low-emissivity film selectively transmits visible light while efficiently blocking infrared heat radiation, achieving a synergistic balance between high light transmittance and heat insulation performance. The silane coupling agent reacts chemically with hydroxyl groups on the glass surface to form covalent bonds, and simultaneously undergoes a cross-linking reaction with the adhesive film resin, constructing a chemical bonding interface between the glass and the adhesive film. This significantly improves the interfacial bonding strength, prevents external water and oxygen from penetrating into the interlayer, and fundamentally avoids interfacial delamination and debonding failure. Cesium bromide and lead bromide were used as precursors to synthesize perovskite quantum dots. Tetraoctylammonium bromide was used as a surface ligand to precisely control the nucleation and growth process of the quantum dots, resulting in quantum dot crystals with uniform size and excellent luminescence efficiency. Tetraethyl orthosilicate was hydrolyzed and condensed under ammonia catalysis to form a dense silica shell on the surface of the quantum dots, isolating them from external water, oxygen, and chemical corrosion, and inhibiting photoquenching and thermal decomposition of the quantum dots. Vinyltriethoxysilane was used to perform surface ligand exchange on the quantum dots, introducing reactive active groups, enhancing the compatibility between the quantum dots and PVB resin, and avoiding the decrease in light transmittance and loss of luminescence efficiency caused by nanoparticle aggregation. The PVB matrix resin served as the bonding and supporting matrix for the sandwich structure. The polymeric dispersant stabilized the dispersion state of the quantum dots in the resin through steric hindrance, ensuring high transparency and uniform light conversion performance of the film. The ultraviolet absorber absorbed most of the harmful ultraviolet light, protecting the quantum dots and film from ultraviolet aging degradation and improving the ultraviolet blocking ability of the curtain wall. The vacuum pre-compression and autoclave curing process, through stepwise heating and pressurization, allows the adhesive film to fully melt and flow, filling the micro-grid structure and forming a strong interfacial bond with mechanical interlocking and chemical bonding. Simultaneously, it completely removes residual air from between layers to prevent bubble formation. The optically transparent adhesive enables efficient light coupling between the glass sides and the perovskite photovoltaic strips, transmitting visible light converted from quantum dots to the photovoltaic strips for stable power generation. Butyl rubber and a double-sealed structure construct a multi-layered water and oxygen barrier, protecting the internal power generation components and adhesive film from external environmental corrosion, significantly improving the product's long-term weather resistance and electrical stability. This achieves the goal of improving the production efficiency of glass curtain walls with power generation capabilities. Its light transmittance is 85.1-89.2%, which is considered to be high light transmittance; its electrical conversion efficiency retention rate is 92.3-97.8%, which is considered to be good weather resistance; and its photoelectric conversion efficiency is 5.02-5.51%, which is considered to be good electrical performance. It is evident that, given a fixed amount of raw materials, the production effect of glass curtain walls with power generation capabilities can be increased by adjusting the proportions of these materials. Based on the data in the table above, it is clear that when preparing the light-conversion functional film, the glass curtain wall with the strongest light transmittance is prepared using 100 parts cesium bromide, 147 parts lead bromide, 6.5 parts tetraoctylammonium bromide, 32 parts tetraethyl orthosilicate, 10 parts ammonia, 4 parts vinyltriethoxysilane, 25,000 parts PVB matrix resin, 30 parts polymeric dispersant, and 25 parts UV absorber. This is because this ratio results in the lowest relative concentration of the quantum dot functional phase and the thinnest SiO2 shell generated by the hydrolysis of tetraethyl orthosilicate, introducing [the desired effect]. The additional interface has the smallest refractive index difference, which maximizes the intrinsic transmittance of the PVB matrix resin. At the same time, although the amount of polymeric dispersant is minimal, the low-concentration quantum dot surface can be completely coated, effectively suppressing the tendency of nanoparticles to aggregate and avoiding light scattering and haze increase caused by agglomerates. In addition, the amount of UV absorber UV-327 is minimal, reducing its trace intrinsic absorption in the visible light band, and ultimately achieving the highest visible light transmittance. Although Example 5 has a thicker silica shell and better quantum dot stability, the free nano-silica particles generated by the excessive hydrolysis of tetraethyl orthosilicate will produce slight Rayleigh scattering, which slightly reduces the transmittance, as obtained from Examples 1-5.

[0035] It is evident that, given a fixed amount of raw materials, the production efficiency of glass curtain walls with power generation capabilities can be increased by adjusting the proportions of these materials. Based on the data in the table above, it is clear that when preparing the light-conversion functional film, the glass curtain wall with the best weather resistance was prepared using 100 parts cesium bromide, 147 parts lead bromide, 8.5 parts tetraoctylammonium bromide, 45 parts tetraethyl orthosilicate, 14 parts ammonia, 6 parts vinyltriethoxysilane, 21,000 parts PVB matrix resin, 54 parts polymeric dispersant, and 35 parts UV absorber. The reason for this is that this ratio results in the highest amounts of tetraethyl orthosilicate and ammonia, leading to the thickest and densest silica shell formed on the quantum dot surface. This shell maximizes the isolation from external water, oxygen, and chemical corrosion, fundamentally inhibiting the thermal decomposition and photoquenching of perovskite quantum dots. The highest amount of tetraoctylammonium bromide is also observed in this formulation. The nucleation and growth process of quantum dots can be precisely controlled to obtain quantum dot crystals with more uniform size and fewer lattice defects, reducing the defect-induced degradation rate during aging. The highest amount of vinyltriethoxysilane can more fully complete the ligand exchange on the quantum dot surface, introduce more reactive groups, significantly enhance the interfacial bonding force between quantum dots and PVB resin, and eliminate water and oxygen permeation channels generated by phase separation. The highest amount of polymeric dispersant can effectively inhibit the tendency of high-concentration quantum dots to agglomerate in the PVB matrix, avoid local defects and stress concentration caused by agglomerates, and ensure uniform distribution of ultraviolet absorbers in the film. The highest amount of ultraviolet absorber UV-327 can absorb most of the incident ultraviolet light, protecting quantum dots from ultraviolet radiation degradation and delaying the yellowing and aging embrittlement of PVB matrix resin, as obtained from Examples 1-5.

[0036] It is evident that, given a fixed amount of raw materials, the production effect of glass curtain walls with power generation capabilities can be increased by adjusting the proportions of these materials. Based on the data in the table above, it is clear that when preparing the light-conversion functional film, the glass curtain wall with the best electrical performance is prepared using 100 parts cesium bromide, 147 parts lead bromide, 8 parts tetraoctylammonium bromide, 42 parts tetraethyl orthosilicate, 13 parts ammonia, 5.5 parts vinyltriethoxysilane, 22,000 parts PVB matrix resin, 48 parts polymeric dispersant, and 32 parts UV absorber. The reason for this is that the amount of PVB matrix resin in this formulation is at the middle level among the five groups, ensuring that the quantum dot concentration per unit volume of the film reaches the optimal balance. This avoids the problems of insufficient UV absorption and low total light conversion caused by excessively low quantum dot concentration, while also resolving the defects of concentration quenching and increased non-radiative recombination caused by excessively high quantum dot concentration. The optimal effective light conversion output was achieved by using a silica shell of moderate thickness formed by tetraethyl orthosilicate and ammonia. This shell provides sufficient water and oxygen barrier to protect the integrity of the quantum dot lattice without hindering energy transfer and photon emission between quantum dots due to excessive thickness. Sufficient tetraoctylammonium bromide ensures the synthesis of perovskite quantum dot crystals with uniform size, few lattice defects, and high quantum yield, reducing defect-induced carrier recombination losses. High amounts of vinyltriethoxysilane and polymeric dispersant guarantee uniform dispersion of high-concentration quantum dots in the PVB matrix, completely suppressing luminescence quenching and light scattering losses caused by nano-agglomeration. The UV absorber UV-327 is precisely matched to the excitation spectrum range of the quantum dots, effectively absorbing harmful deep ultraviolet light to protect the quantum dots and matrix resin without excessively absorbing near-ultraviolet light suitable for quantum dot excitation, maximizing the retention of the effective excitation source, as obtained in Examples 1-5.

[0039] Table: Performance test results of light transmittance, electro-conversion efficiency retention rate, and photoelectric conversion efficiency in Examples 1 and 6-9 As can be seen from the table above, the preparation processes of the power-generating glass curtain walls in Examples 1 and 6-9 all effectively improve the production efficiency of power-generating glass curtain walls.

This achieves the goal of improving the production efficiency of glass curtain walls with power generation capabilities. Its light transmittance is 82.3-89.2%, which is considered to be high light transmittance; its electrical conversion efficiency retention rate is 90.2-92.3%, which is considered to be good weather resistance; and its photoelectric conversion efficiency is 5.0-5.8%, which is considered to be good electrical performance. It is evident that, given a fixed amount of raw materials, the production effect of glass curtain walls with power generation capabilities can be increased by adjusting the preparation conditions. Based on the data in the table above, it is clear that when preparing light-conversion functional films, increasing the stirring temperature, heating temperature, and holding time during the preparation of the quantum dot crystal structure, as well as the surface ligand exchange process temperature and stirring time, initially improves and then decreases the light transmittance, weather resistance, and electrical properties of the resulting glass curtain wall with power generation capabilities. The quantum dot crystal structure preparation process involves stirring for 30 minutes at a holding temperature of 120℃ and a rotation speed of 400 r / min, followed by heating to 160℃ and injecting tetraoctylammonium bromide, then holding the reaction for 5 minutes. The surface ligand exchange process is carried out at a temperature of 100℃... The glass curtain wall with power generation function prepared by stirring under a nitrogen atmosphere for 2 hours exhibited the highest light transmittance, weather resistance, and electrical performance. The reason for this is that during the preparation of quantum dots with crystal structure, insufficient heat preservation temperature and stirring time lead to incomplete dehydration and decarboxylation reactions of the precursor, uneven nucleation process, and easy generation of a large number of lattice defects and quantum dots with uneven size, resulting in reduced luminous efficiency and enhanced light scattering. On the other hand, when the temperature is too high or the heat preservation time is too long, the quantum dots will undergo Ostwald ripening, resulting in overgrowth and widening of the particle size distribution. Large-sized quantum dots will cause severe Rayleigh scattering. At the same time, high temperature will destroy the stable adsorption of surface ligands and increase the risk of quantum dot aggregation. Both of these factors will lead to a decrease in light transmittance and power generation performance. During surface ligand exchange, if the temperature is too low or the reaction time is insufficient, vinyltriethoxysilane cannot completely replace the oleic acid ligands on the surface of quantum dots. This results in poor interfacial compatibility between quantum dots and PVB resin, leading to phase separation and aggregation. This not only reduces light transmittance but also creates water-oxygen permeation channels, accelerating aging and degradation. Conversely, if the temperature is too high or the reaction time is too long, excessive ligand reaction and surface ligand detachment occur, damaging the surface passivation layer of the quantum dots. This leads to increased lattice defects and exacerbated photoquenching. Furthermore, high temperatures cause aggregation and crystal transformation of quantum dots, severely impairing their light conversion performance and weather resistance. Under optimal process conditions, quantum dot nucleation synchronization is best, crystal defects are fewest, size distribution is narrowest, and surface ligand exchange is complete and firmly bonded. This ensures uniform dispersion and no aggregation of quantum dots in the PVB matrix, achieving the highest visible light transmittance, while maximizing the quantum yield and light conversion efficiency. Simultaneously, complete surface passivation and interfacial bonding significantly improve the water-oxygen barrier capacity and anti-aging properties of the quantum dots, as obtained in Examples 1 and 6-9.

The average value of the test results is recorded in the table below.

As can be seen from the table above, the preparation processes of the power-generating glass curtain walls in Examples 1 and 10-11 all effectively improve the production efficiency of glass curtain walls with power generation functions. Ultra-white float glass, as the load-bearing substrate of the curtain wall, reduces the intrinsic absorption of visible light due to its low-iron properties.

This achieves the goal of improving the production efficiency of glass curtain walls with power generation capabilities. Its light transmittance is 86.4-89.2%, which is considered to be high light transmittance; its electrical conversion efficiency retention rate is 90.8-92.3%, which is considered to be good weather resistance; and its photoelectric conversion efficiency is 5.1-5.8%, which is considered to be good electrical performance. It is evident that, given a fixed amount of raw materials, the production effect of glass curtain walls with power generation capabilities can be increased by adjusting the preparation conditions. Based on the data in the table above, it is clear that when preparing modified glass substrates, increasing the heating rate, heating temperature, holding time, and wind pressure during the tempered glass substrate preparation process initially improves and then decreases the light transmittance, weather resistance, and electrical properties of the resulting glass curtain walls with power generation capabilities. For example, a tempered glass substrate prepared by heating to 650℃ at a rate of 20℃ / min, holding for 90s, and then rapidly quenching to room temperature with compressed air at a wind pressure of 10KPa yields a glass curtain wall with power generation capabilities that... Glass curtain walls with electrical functions have the highest light transmittance, weather resistance, and electrical performance. The reason for this is that during the tempered glass substrate preparation process, if the heating rate is too low, the glass stays in the high-temperature zone for too long, which easily causes surface crystallization and iron ion oxidation, resulting in a decrease in visible light transmittance. At the same time, excessively long high-temperature treatment will cause thermal deformation of the micro-grid structure formed by laser etching, destroying the mechanical anchoring interface with the subsequent film. If the heating rate is too high, the temperature difference between the inside and outside of the glass is too large, which will generate uneven thermal stress, causing the glass to warp and deform or even crack. Uneven distribution of internal stress will also reduce the glass's impact resistance and weather resistance stability. When the insulation temperature is too low or the insulation time is insufficient, the glass does not reach a uniform softening state, atomic rearrangement is incomplete, the surface compressive stress layer formed after tempering is too thin and unevenly distributed, and the mechanical strength and wind pressure resistance are insufficient. It is prone to microcracks under changes in ambient temperature, becoming channels for water and oxygen penetration. When the insulation temperature is too high or the insulation time is too long, the glass softens excessively, resulting in severe dimensional deformation and surface flow. The microstructure etched by laser completely fails, and the high temperature will exacerbate the expansion of internal defects in the glass, reducing light transmittance and structural stability. When the quenching air pressure is too low, the cooling rate is insufficient, and a sufficiently strong surface compressive stress layer cannot be formed, resulting in poor tempering effect, easy breakage of the glass, and poor weather resistance. When the quenching air pressure is too high, the excessively rapid cooling will cause a large number of microcracks to form on the glass surface. This will not only scatter light and reduce light transmittance, but also become a rapid channel for external water and oxygen intrusion, accelerating the aging and degradation of the internal film and power generation components. Under optimal process conditions, the glass is heated uniformly and the atoms rearrange fully, resulting in a uniform and suitable surface compressive stress layer. This ensures the glass's excellent mechanical properties and anti-aging ability, while also preserving the micro-grid structure of laser etching. At the same time, it avoids crystallization, oxidation, and microcracks, providing an ideal substrate for subsequent interface modification and sandwich composites, as obtained in Examples 1 and 10-11.
