Abstract

The invention relates to a processing method for improving a solar cell work stability and a device thereof comprising: irradiating a solar cell or a solar cell film by using a laser with a spectral wave length of 10. 06 micron so as to make an internal crystal phase arrangement of the solar cell or the solar cell film to tend to consistent, usefully improving and stabilizing the light energy absorption efficiency, the electric energy conversion efficiency and the output power of the solar cell, implementing the improvement of the attenuation of the output power and improving the work stability and prolonging the effective work life interval. The device comprises an operation control box, a CO2 laser generator and a work piece irradiation table. The operation control box and the CO2 laser generator are interconnected by conductors. The CO2 laser generator and the work piece irradiation table are interconnected by a light path. The solar cell or the solar cell film is arranged on the work piece table for irradiation. The output power attenuation of the solar cell made after the processing is less than 5, the effective work life interval is at least prolonged to 40 years so as to satisfy any special use demands.

Description

technical field [0001] The invention relates to the technical field of manufacturing electronic components, in particular to a processing method and a device for improving the working stability of solar cells. Background technique [0002] Solar energy is an inexhaustible renewable energy source for human beings, and it is also a clean energy source that does not produce any environmental pollution. How to use solar energy more effectively is currently the most watched and most dynamic research topic, and it is also one of the fastest-growing projects in recent years. The utilization of solar energy is based on semiconductor photoelectric materials, and solar cells have been developed and developed by using the characteristics of photoelectric conversion reactions after photoelectric materials absorb light energy. The basic building block of a solar cell is actually a semiconductor photodiode. When sunlight hits the photodiode, the photodiode converts the sun's light energy...
