Problems solved by technology

Although this stacking method can obtain more solar energy, the multiple material layers will inevitably increase the manufacturing cost of the battery sheet and the yield rate will be low, and the structure of the entire photovoltaic battery panel is more complicated, and the finished product is heavier. Not conducive to installation by installers

Abstract

The invention provides a double-face photovoltaic cell. The double-face photovoltaic cell comprises a first protective layer, a photovoltaic cell and a reflecting member used for receiving and reflecting sun rays. There are multiple double-face photovoltaic cells. Gaps are present between adjacent double-face photovoltaic cells. The reflecting member is arranged under the gaps and makes received sun rays reflected to the lower surfaces of the double-face photovoltaic cells. The reflecting member is a second protective layer. The lower surface of the second protective layer is a planar surface while the upper surface is a curved surface. A reflecting coating layer is coated on the curved surface. The first protective layer and the second protective layer are connected in a sealing way to form a sealed chamber. A plurality of double-face photovoltaic cells are arranged inside the sealed chamber. By means of the reflecting members arranged under the gap located between adjacent double-face photovoltaic cells, sun rays emitted in the gap are reflected. The reflecting members are protective layers and achieve protection. Reflection is further achieved through the reflecting coating layer on the curved surface. The weight of the whole photovoltaic cell is reduced. Meanwhile, the double-face photovoltaic cell has a simple structure.

Description

technical field [0001] The invention relates to the field of production capacity of solar photovoltaic cells, in particular to a double-sided photovoltaic cell. Background technique [0002] With the development of society and science and technology, the production technology of solar panels has been continuously improved, and has been widely used in various fields. Solar photovoltaic cells (referred to as photovoltaic cells) are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. It is a solar battery combination device with packaging and internal connection that can provide direct current output alone, and the solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Not only can the solar energy be converted into electrical energy, or sent to the storage battery for storage, or to promote the load to work. [0003] ...
