Laser photovoltaic cell and manufacturing method thereof

Abstract

The invention discloses a laser photovoltaic cell which includes an isolation tank. The isolation tank is used for dividing the laser photovoltaic cell into a plurality of battery units. The battery units are connected in series. A polyimide layer, a dielectric film layer and a metal shading layer are formed in sequence on the surface of inwall of the isolation tank. The invention also discloses a manufacturing method thereof. According to the invention, electricity leakage problem due to semi-insulating substrate illumination is solved. The manufactured photovoltaic cell has the advantages of high parallel resistance, small electricity leakage and the high conversion efficiency.

Description

technical field

[0001] The invention relates to a laser photovoltaic cell, in particular to a GaAs laser photovoltaic cell based on a novel isolation filling process and a manufacturing method thereof. Background technique

[0002] The laser energy supply system is an innovative energy transfer system. With this system, the light emitted by the laser source is transmitted to the laser photovoltaic cell through the optical fiber, which can provide a stable power output. The conversion of light into electricity through optical fiber has more advantages than traditional metal wire and coaxial cable power transmission technology, and can be applied in radio communication, industry where electromagnetic interference needs to be eliminated or electronic devices need to be isolated from the surrounding environment. There are important applications in the directions of sensors, national defense, aviation, medicine, and energy. The working principle of laser photovoltaic cells is si...
