Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic technology, in particular to a solar photovoltaic panel and a photovoltaic power generation blind. Background Art

[0002] Solar panels are a type of photoelectric semiconductor sheet that uses sunlight to generate electricity directly. They are also called "solar chips" or "photovoltaics". As long as they are illuminated under certain conditions, they can instantly output voltage and generate current in the presence of a circuit. In physics, this is called solar photovoltaics (abbreviated as PV), or photovoltaics for short.

[0003] Solar power shutters are a new type of architectural design that can provide shading, adjust indoor light levels, and convert sunlight into electricity for use inside the building. By embedding solar panels into the structure of the shutters, it can use solar energy to convert light into electricity. At the same time, the adjustability of the shutters allows the building to reduce sunlight while maintaining light, lowering the temperature inside the building, thereby reducing energy consumption for cooling and heating. Such a design can not only provide self-sufficient electricity for the building, but also improve energy efficiency and reduce energy consumption, thereby reducing negative impacts on the environment.

[0004] Currently, most of the materials of blinds on the market are aluminum alloy, stainless steel, solid wood, plastic, etc. As for power-generating blinds, their blades are only a medium that carries solar cells. When sunlight shines, they absorb solar energy and convert it into electrical energy, but they still cannot prevent the entry of ultraviolet rays. Moreover, the color is relatively single, which cannot have a good decorative effect on the exterior walls of buildings. Utility Model Content

[0035] like Figure 1 As shown, the utility model provides a photovoltaic power generation blind, comprising a window frame 6, a plurality of blades 7 rotatably mounted in the window frame 6, and a driving mechanism for driving the blades 7 to rotate synchronously.

[0036] The blade 7 is made of solar photovoltaic panels. Figure 2As shown, the solar photovoltaic panel includes a substrate 1, an electron transport layer 2, a perovskite light absorption layer 3, a hole transport layer 4 and a transparent electrode layer 5 arranged in sequence from the inside to the outside, wherein the substrate 1 is made of a titanium sheet, and the electron transport layer 2 is made of titanium dioxide, which is obtained by surface oxidation of the titanium sheet. The band gap of the perovskite light absorption layer 3 is 1.5eV-3.5eV, which can realize the absorption and emission of different bands of visible light, thereby achieving color change.

[0037] Specifically, the hole transport layer 4 can be made of poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine], 3-hexylthiophene polymer, 2PACz, MeO-2PACz, Me-4PACz or Me-2PACz, etc., and its work function needs to be lower than 4.5eV-4.8eV, in order to achieve higher power conversion efficiency of solar cells. Preferably, the work function of the hole transport layer 4 is lower than that of the transparent electrode layer 5, which is conducive to the transmission of holes.

[0038] In this embodiment, the transparent electrode layer 5 is an indium tin oxide transparent conductive electrode, which can effectively absorb sunlight and increase the incident light power density.

[0039] The blades 7 of the photovoltaic shutters in this embodiment are made of the aforementioned solar photovoltaic panels, which use titanium sheets as substrates and also serve as electrodes of solar cells. The titanium sheets are oxidized to form titanium dioxide as the electron transport layer of the solar cell. At the same time, titanium dioxide can effectively block the entry of ultraviolet rays. The perovskite light absorption layer can be designed as perovskite materials with different band gaps, which can achieve emission of different bands of visible light, thereby achieving color change. Therefore, the photovoltaic shutters of this application can not only effectively block the entry of ultraviolet rays, but also achieve color change of the shutters, which has a better decorative effect on the exterior walls of buildings.

[0040] The present application uses a titanium sheet as the substrate 1 of the solar photovoltaic panel, so that the blade 7 has a flexible property and can adjust the amplitude and angle at will. At the same time, the surface of the titanium sheet can be oxidized to obtain titanium dioxide, eliminating the trouble of coating titanium dioxide on the substrate 1 of the traditional perovskite solar photovoltaic panel, simplifying the manufacturing process and reducing the manufacturing cost.

[0041] Specifically, Figure 3As shown, the two ends of the blade 7 have a rotating shaft 8 extending outward, and the rotating shaft 8 is rotatably installed in the window frame 6 through a bearing, and a transmission wheel 9 is arranged on one end of the rotating shaft 8 that penetrates into the window frame 6. The driving mechanism is arranged in the installation cavity at the bottom of the window frame 6, and the driving mechanism includes a transmission shaft 10 and a driving module for driving the transmission shaft 10 to rotate. The two ends of the transmission shaft 10 are provided with bearing seats 11, and the bearing seats 11 are fixedly installed on the inner wall of the installation cavity by bolts, so that the transmission shaft 10 can rotate axially, and the transmission shaft 10 is arranged horizontally. A driving wheel 12 is installed at both ends of the transmission shaft 10, and the driving wheel 12 is connected to the corresponding transmission wheel 9 through a transmission bar 13. The driving module drives the transmission shaft 10 to rotate, and the driving wheel 12 drives the transmission bar 13 to rotate, thereby driving the transmission wheel 9 to rotate, and the transmission wheel 9 drives the blade 7 to rotate through the rotating shaft 8, so as to achieve the purpose of opening or closing the blinds.

[0042] In this embodiment, the driving wheel 12 and the transmission wheel 9 can both be gears or sprockets, and correspondingly, the transmission bar 13 can be a toothed belt or a chain.

[0043] In this embodiment, the driving module includes a servo motor 14 and a controller electrically connected to the servo motor 14. A worm 15 is connected to the output shaft of the servo motor 14, and a worm wheel 16 is provided in the middle of the transmission shaft 10, and the worm wheel 16 is meshed with the worm 15. The servo motor 14 drives the worm wheel 16 to rotate through the worm 15, thereby driving the transmission shaft 10 to rotate, and the self-locking function of the worm wheel 16 and the worm 15 is used to ensure that the blade 7 can be maintained in different opening and closing states.

[0044] In this embodiment, the controller includes an infrared receiving head 17 and a single chip microcomputer 18, the infrared receiving head 17 and the single chip microcomputer 18 are electrically connected, and the servo motor 14 is electrically connected to the single chip microcomputer 18. The infrared receiving head 17 is embedded on the outer wall of the window frame 6, and is used to receive the infrared remote control signal transmitted by the user through the remote control, convert the infrared remote control signal into an electrical signal and send it to the single chip microcomputer 18. The single chip microcomputer 18 controls the rotation direction and number of rotations of the servo motor 14 according to the infrared remote control signal, so as to control and adjust the opening and closing state of the photovoltaic shutter.
