Description

TECHNICAL FIELD

[0001] The present application relates to a photoelectric module structure and a manufacturing method thereof, in particular, to a photoelectric module structure and a manufacturing method thereof capable of increasing power generation efficiency. BACKGROUND

[0002] The photoelectric module increases the back reflection film, which is an effective technology, and can effectively improve the photoelectric conversion efficiency of the photoelectric module. The photoelectric module sets the reflection film, so that the light that is not completely absorbed is reflected back into the solar cell for re-absorption (secondary absorption), thereby improving the photoelectric conversion efficiency of the solar cell. In various optical and optical element devices, for example, a solar cell module, Figure 1 For the cross-sectional view of the prior art photoelectric module, please refer to Figure 1 The prior art is a reflection film structure element (92) combined with a double hollow suspension film technology on a photoelectric element (91). Specifically, the photoelectric element (91) includes a first glass (911), a solar power generation structure (912), and a second glass (913) stacked in sequence, and the reflection film structure element (92) has a glass substrate (921) and a reflection layer (922) stacked together. The light entrance surface (911) of the first glass (911) of the photoelectric element (91) allows light (94) to enter the solar cell module. Figure 1 The reflection layer (922) of the prior art can actually be a structure composed of two hollow layers (9221) sandwiching a reflection film (9222). Although the reflection layer (922) can block heat conduction and increase reflection / power generation efficiency by using secondary absorption, the reflection film (9222) is often made of metal material and is prone to oxidation and degradation. Therefore, a double hollow structure with complicated process steps is needed to protect the reflection layer (922), which takes a very long time to complete a piece, even 1-2 weeks. However, the double hollow structure leads to a very thick overall structure, which is not conducive to the production of thin and small size.

[0003] Due to the difference in heat energy and stress growth between the glass substrate (921) and the reflection layer (922), the coating of the reflection layer (922) will generate residual stress. When depositing a thin film on the glass substrate (921), the difference in thermal expansion between the glass substrate (921) and the reflection layer (922) also generates the origin of thermal stress. Because of the generation of residual stress, the growing reflection layer (922) will have a situation of damage and cracking. The prior art solves the above problems by adjusting the process parameter range to reduce the growth of cracks, but this solution limits the selection of the reflection layer (922) material.

[0004] In addition, the glass substrate (921) of the aforementioned photoelectric module is often installed on a curved surface, and thus needs to be bent into a curved surface or directly produced as a curved glass substrate (921). In the case of a bent glass substrate (921), when the glass substrate (921) with the reflective layer (922) is subjected to heat bending processing, after the glass substrate (921) is heat-bent, when the heat-bending curvature is less than a certain radius, the coating layer on the outside of the curved surface of the reflective layer (922) of the glass substrate (921) will be stretched, and thus obvious tensile cracks will occur, which will easily cause the reflective layer (922) to break.

[0005] In another aspect, the aforementioned photoelectric module of the prior art uses three layers of glass, which will lead to an increase in the weight and thickness of the entire module, and the structure of the prior art cannot improve the reflection effect and cannot improve the light collection, and thus the power generation efficiency of the photoelectric module is difficult to improve.

[0006] Therefore, the prior art still needs to be improved. SUMMARY

Figure 4 and Figure 5 As shown, this embodiment is Figure 2 The manufacturing method of the structural embodiment, Figure 2 The arrows shown on the left side of the diagram indicate the manufacturing direction of the structure. The steps include providing a photoelectric element (S10), providing a reflective film structure element (S11), and bonding (S12). The step of providing a photoelectric element (S10) involves sequentially stacking a first glass substrate, a solar power generation structure, and a second glass substrate to form a photoelectric element.

Figure 3 and Figure 6 As shown, this embodiment is Figure 3 The manufacturing method of the structural embodiment, Figure 3 The arrows shown on the left side of the figure indicate the manufacturing direction of the structure. The steps include providing a reflective film structural element (S20) and forming a photoelectric module (S21): the step of providing a reflective film structural element (S20) involves sequentially stacking a glass substrate, an auxiliary layer, and a reflective layer to form a reflective film structural element; the step of forming a photoelectric module (S21) involves forming a solar power generation structure on the outer surface of the reflective layer, and then bonding a glass with a resin on the outer surface of the solar power generation structure to form a photoelectric module, wherein the outer surface of the glass is the light-incident surface.

[0040] It is worth mentioning that the aforementioned Figure 2 、 Figure 5 embodiments of the 3-piece glass photoelectric module structure and method of the present application, when performing the heat bending process, due to the effect of the auxiliary layer, the reflective layer is less likely to be broken, and due to the improved reflection effect of the reflective layer of the photoelectric module, the photoelectric module of the present application can absorb secondary light reflection, and has higher power generation efficiency than the prior art. In addition, compared with the aforementioned Figure 2 、 Figure 5 embodiments, the aforementioned Figure 3 、 Figure 6 embodiments of the 2-piece glass photoelectric module structure, due to the reduction of one piece of glass, are lighter in weight and less in cost, but still have the same reflective layer that is not easy to break during the heat bending process and higher power generation efficiency. In addition, compared with the aforementioned Figure 2 、 Figure 5 embodiments of the 3-piece glass type, the aforementioned Figure 4 、 Figure 7 embodiments of the 2-piece glass photoelectric module structure are also lighter in weight, less in cost, have a reflective layer that is not easy to break during the heat bending process, and have higher power generation efficiency, and are better than Figure 3 、 Figure 6 embodiments because Figure 3 、 Figure 6 embodiments form the solar power generation structure on the reflective layer, which affects the material of the reflective layer (reflective film) structure, resulting in a decrease in the reflection effect of the reflective film. In contrast, the Figure 4 、 Figure 7 embodiments can combine the reflective film structure element after forming the solar power generation structure, thus avoiding a decrease in the reflection effect.

[0041] Preferably, in each method embodiment, the resin material is polyethylene-vinyl acetate copolymer, and the polyethylene-vinyl acetate copolymer material has adhesion, so it can be used as a gluing material. The resin combination structure is a solid gluing layer or a hollow joint layer (the gluing process is simple but has heat conduction problems, the hollow joint process is more difficult but has low heat conduction, and both processes have their own advantages).

[0042] It is worth mentioning that in the present application, the auxiliary layer (22) of the reflective film structure element (20) is formed on the glass substrate (21) by a plasma sputtering method. The material of the auxiliary layer (22) can include silicon dioxide (SiO2), fluorine-doped tin oxide (FTO), co-doped tin oxide (LFTO), aluminum-doped zinc oxide (AZO), antimony tin oxide (ATO), indium tin oxide (ITO), or indium gallium zinc oxide (IGZO). The auxiliary layer (22) has preferable properties of bendability and adhesion, and the plasma sputtering forming process can make the auxiliary layer (22) have a buffering property to offset the stress accumulated in the reflective layer (23) during the heat bending process, thereby reducing or even avoiding the problem of breakage of the reflective layer during the heat bending process. In addition, the interface between the auxiliary layer and the reflective layer formed by the heat process can be further optimized, and the material of the auxiliary layer and the reflective layer can be recrystallized, so that the optical reflection effect is improved.

[0043] Preferably, the resin bonding process in each embodiment of the present application is a low-temperature bonding process using polyethylene-vinyl acetate copolymer (EVA) resin material. It is worth mentioning that the low-temperature bonding packaging technology of the resin is commonly used in the bonding glass packaging in the field of solar cells. The curing temperature of the polyethylene-vinyl acetate copolymer is generally above 130 degrees, the low-temperature polyethylene-vinyl acetate copolymer can be cured below 100 degrees, and the cured material has high light transmittance (90%) and can resist ultraviolet light below 385 nm. Therefore, the advantages of using low-temperature bonding process in the resin bonding process include low cost, low carbon emission, and no degradation of the third-generation solar cell, etc.

[0044] Preferably, in each of the above embodiments, the resin material is selected from the group consisting of polyethylene-vinyl acetate copolymer (EVA), polyvinyl butyral (PVB), polyolefin elastomer (POE), and thermoplastic elastomer (TPE).

[0045] In summary, the features of the present application include: adding an auxiliary layer with a buffering property in the reflective film structure element as a forming substrate of the reflective film structure to overcome the problem of breakage of the reflective film structure element during the heat bending process. The present application also applies a heat process to optimize the interface between the auxiliary layer and the reflective layer to further improve the reflectivity of the reflective film structure element (for example, an increase of 10%), which can improve the power generation efficiency of the applied photovoltaic module structure. The present application can also reduce the use of glass in the photovoltaic module structure, which can be reduced to 3 pieces or 2 pieces, but still has the functions of strong and unbreakable reflective film and high power generation efficiency, etc.

[0046] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application.
