Description

Technical Field

[0001] This utility model relates to the field of road equipment technology, and in particular to a photovoltaic anti-glare panel and a photovoltaic power generation system. Background Technology

[0002] Anti-glare panels are traffic safety products installed on the median strip of highways to solve the problem of glare from oncoming vehicle headlights. Traditional anti-glare panels only block or reduce the high beams of oncoming vehicles, offering a relatively simple function. However, road medians generally have the advantages of ample sunlight and no tall buildings obstructing the view, making them ideal areas for installing photovoltaic (PV) power generation equipment. Most existing PV anti-glare panels are made of crystalline silicon photovoltaic cells, which offer significant power generation advantages under sunny conditions, but cannot guarantee power generation during cloudy or rainy weather. Utility Model Content

[0003] Therefore, it is necessary to provide a photovoltaic anti-glare panel and photovoltaic power generation system to address the problems of limited functionality of traditional anti-glare panels and low power generation of crystalline silicon photovoltaic anti-glare panels on cloudy or rainy days.

[0004] A photovoltaic anti-glare panel includes a panel unit one and a panel unit two; the upper end of the panel unit one is fixedly connected or rotatably connected to the upper end of the panel unit two; both the panel unit one and the panel unit two include photovoltaic modules.

[0005] The aforementioned photovoltaic anti-glare panel, with panel unit one and panel unit two forming a structure that provides mutual support, gives the anti-glare panel more robust impact resistance and wind resistance. Simultaneously, this photovoltaic anti-glare panel can also provide supplemental power to electrical equipment near the road, making full use of the characteristics of the road median strip, thus achieving energy conservation and environmental protection.

[0006] In one embodiment, the connection method of the upper ends of the panel unit one and the panel unit two includes, but is not limited to, tenon joint, riveting, welding, bonding, hinge, locking connection, threaded connection, bolt connection, and bolting.

[0007] In one embodiment, the photovoltaic anti-glare panel further includes a base, which is fixedly or rotatably connected to the lower ends of panel unit one and panel unit two.

[0008] In one embodiment, the base is also provided with a junction box and power transmission lines.

[0009] In one embodiment, the photovoltaic anti-glare device further includes a connector, which is disposed at the upper end of panel unit one and / or the upper end of panel unit two, and panel unit one and panel unit two are fixedly connected or rotatably connected by the connector.

[0010] In one embodiment, panel unit one and / or panel unit two further include a frame. The frame may be an aluminum frame or a weather-resistant resin frame.

[0011] In one embodiment, the photovoltaic module includes a glass layer, a first flexible substrate layer, a thin-film photovoltaic cell, a second flexible substrate layer, and the glass layer stacked sequentially. The photovoltaic module of this invention has glass on both the front and back sides, thus offering better wear resistance and insulation. Furthermore, both the front and back sides of the photovoltaic module can absorb light, resulting in a higher total power generation than a single-glass module.

[0012] In one embodiment, the first flexible substrate layer includes at least one of EVA film, POE film, and EPE film; the second flexible substrate layer includes at least one of EVA film, POE film, and EPE film.

[0013] In one embodiment, the glass layer comprises tempered glass.

[0014] In one embodiment, the thin-film photovoltaic cell is a perovskite thin-film photovoltaic cell.

[0015] In one embodiment, the band gap of the thin-film photovoltaic cell is 1.2 eV to 2.3 eV.

[0016] In one embodiment, the perovskite thin-film photovoltaic cell includes a conductive glass, a first charge transport layer, a perovskite light-absorbing layer, a second charge transport layer, and a back electrode, which are stacked sequentially.

[0017] In one embodiment, the coating on the conductive glass is a transparent conductive coating, including at least one of FTO (fluorine-doped tin dioxide) and ITO (indium-doped tin dioxide).

[0018] In one embodiment, the first charge transport layer is a hole transport layer and the second charge transport layer is an electron transport layer.

[0019] In one embodiment, the back electrode is a transparent electrode layer or a semi-transparent metal electrode layer.

[0020] The power generation efficiency of photovoltaic cells under low light is related to the band gap. When the band gap is close to 2 eV, the power generation efficiency of photovoltaic cells under low light can reach as high as 52%. Perovskite materials, with their tunable band gap, high light absorption coefficient, and insensitivity to impurities, still exhibit outstanding photoelectric conversion efficiency under low light. Perovskite thin-film photovoltaic cells can still output a photoelectric conversion efficiency of over 25% under 200 Lux of low light. In contrast, crystalline silicon has a single band gap of approximately 1.1 eV, resulting in extremely low power generation efficiency under low light.

[0021] The adjustable bandgap of perovskite materials, combined with the structure of the photovoltaic anti-glare panel of this invention, allows perovskite thin-film photovoltaic cells with different bandgapes to be installed on different panel units, enabling the photovoltaic anti-glare panel to adapt to any weather and generate electricity.

[0022] In one embodiment, the angle between the extension plane of panel unit one and the extension plane of panel unit two is 1° to 150°.

[0023] In one embodiment, the angle between the extension plane of panel unit one and the extension plane of panel unit two is 30° to 120°.

[0024] This utility model also provides a photovoltaic power generation system, including the photovoltaic anti-glare panel as described in any of the preceding claims.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This utility model discloses a photovoltaic anti-glare panel and photovoltaic power generation system. Panel unit one and panel unit two form a structure that provides mutual support, giving the anti-glare panel greater stability and wind resistance. Simultaneously, this photovoltaic anti-glare panel can provide supplemental power to electrical equipment near the road, fully utilizing the characteristics of road medians, thus achieving energy conservation and environmental protection. The photovoltaic module in this utility model has glass on both sides, resulting in better wear resistance and insulation. Furthermore, both the front and back of the photovoltaic module can absorb light, leading to a higher total power generation than single-glass modules. The adjustable bandgap characteristic of perovskite material, combined with the structure of this photovoltaic anti-glare panel, allows for the installation of perovskite thin-film photovoltaic cells with different bandgapes on different panel units, enabling the photovoltaic anti-glare panel to adapt to any weather conditions and generate electricity.
