technical field

   The utility model relates to a solar battery panel, in particular to a high-efficiency translucent solar battery panel.

Background technique

With the global energy crisis and environmental problems becoming more and more serious, people pay more and more attention to solar energy, a new energy source, and its application is becoming more and more extensive. The most basic unit of solar photovoltaic power generation is a solar cell. In specific applications, a plurality of solar cells are usually used to form a solar panel. The existing solar panel is made of ultra-white low-iron tempered glass, EVA, solar cells, back These components are heated under vacuum to form a whole. The solar panels currently on the market mainly include the following types: one is the traditional solar panel using a white backsheet, and the other is a solar panel using a black backsheet. Solar panels, these two components are opaque and are mainly used outdoors; there is also a light-transmitting solar panel used on building curtain walls, which are directly exposed to the sun at the same time, and the efficiency is not high , light concentrating is not strong, but in lighting ceilings, carports and other occasions, both sunshade and light transmission are required. Obviously, the solar modules on the market cannot meet the requirements.

Utility model content

The purpose of the utility model is to provide a high-efficiency translucent solar panel with strong light concentrating.

The purpose of this utility model is achieved in the following ways:

A high-efficiency semi-transparent solar cell panel, including an ultra-white and low-iron tempered glass layer, a first EVA layer, a solar cell energy-collecting layer, a second EVA layer and The back sheet layer, the back sheet layer is composed of a translucent back sheet, and a solar energy collecting plate is arranged above the solar cell panel, and the solar energy collecting plate is composed of a light-transmitting layer and a lens layer, and the light-transmitting The layer is correspondingly arranged directly above the lens layer.

Further, the solar cell energy collection layer is composed of polycrystalline silicon solar cells.

Further, the material of the back plate layer is polyvinyl fluoride composite film.

Further, the light-transmitting layer is translucent, and the inner surface forms several concave arc-shaped light-gathering surfaces, and the concave-arc-shaped light-gathering surfaces are continuous concave arc groove surfaces.

Further, the lens layer is provided with several convex lenses corresponding to the concave arc-shaped light-gathering surface.

  The beneficial effects of the utility model are: compared with the traditional solar panel, this product can block the strong outdoor sunlight to a certain extent, making the transmitted light softer and more comfortable, and is especially suitable for use in some buildings. It is widely used in lighting ceilings, carports and other occasions. At the same time, a solar collector is added to collect solar energy by using the light-transmitting layer and the lens layer, so that the solar panel can achieve higher efficiency and generate higher benefits. At the same time, it can reduce The use of energy-collecting components can reduce the cost of using solar energy.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Based on the embodiments of the utility model, all embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the utility model range.

In this embodiment, referring to Fig. 1 and Fig. 2, a high-efficiency semi-transparent solar cell panel includes an ultra-white low-iron tempered glass layer 2 and a first EVA layer arranged in an aluminum alloy frame and arranged sequentially from top to bottom. 3. The solar cell energy collection layer 4, the second EVA layer 5 and the back sheet layer 6 are combined to form a solar cell panel 11, and the back sheet layer 6 is composed of a translucent back sheet and is arranged above the solar cell panel 11 There is a solar energy collecting board 1, and the solar energy collecting board 1 is composed of a light-transmitting layer 7 and a lens layer 8, and the light-transmitting layer 7 is correspondingly arranged directly above the lens layer 8, and the size of the solar energy collecting board 1 is the same as that of the solar cell The plates are equal and are fixedly connected with the solar panel 11.

In addition, the solar cell energy collection layer 4 is composed of polycrystalline silicon solar cells, the material of the back sheet layer 6 is a polyvinyl fluoride composite film, the light-transmitting layer 7 is translucent, and the inner surface forms several concave arcs The light collecting surface 9 is a continuous concave arc groove surface, and the lens layer 8 is provided with several convex lenses 10 corresponding to the concave arc light collecting surface 9 .

  Compared with traditional solar panels, this new product can block the strong outdoor sunlight to a certain extent, making the transmitted light softer and more comfortable. It is especially suitable for lighting ceilings and carports of some buildings. Occasionally, it is widely used. At the same time, a solar collector is added to collect solar energy by using the light-transmitting layer 7 and the lens layer 8, so that the solar panel 11 can achieve higher efficiency and generate higher benefits, and at the same time reduce the cost of the energy-collecting member. use, and can reduce the cost of using solar energy.
