Problems solved by technology

Among them, thin-film solar technology has begun to rise in recent years. CdTe is recognized as a high-efficiency and cheap thin-film battery material, and it is also a compound semiconductor thin-film solar cell with rapid development. However, the existing solar cells are only used as light energy converters to convert solar energy. For the output of electric energy, the current research on solar energy is only how to improve the conversion rate, and the storage of electric energy is only an external energy storage device with a single function. Because the external device is not easy to carry, it directly limits the development of miniaturization of solar cells.

Abstract

The invention discloses an energy-stored photoelectric CdTe (Cadmium Telluride) solar cell and a manufacturing method for the energy-stored photoelectric CdTe solar cell. The solar cell is sequentially provided with a top surface conducting glass substrate (1), a CdTe electricity storage layer (2), a first electrolyte layer (3), a diaphragm (4), a second electrolyte layer (5), an electricity storage layer (6) and a bottom surface conducting glass substrate (7) from top to bottom, wherein the CdTe electricity storage layer (2) is obtained in a manner that CdTe and energy storage materials are uniformly mixed by mass ratio of 5:10 to 24 and then sprayed on a conducting surface of the top surface conducting glass substrate (1); and the electricity storage layer (6) is obtained in a manner that the energy storage materials are sprayed or deposited on a conducting surface of the bottom surface conducting glass substrate (7). According to the energy-stored photoelectric CdTe solar cell provided by the invention, without additional electricity storage devices, the energy-stored photoelectric CdTe solar cell has double functions of photo-electricity conversion and electric energy storage in the same structure as well as a non-light-energy charging function.
