Abstract
The invention discloses a method for improving the stability of a cadmium telluride battery, comprising the following steps: S1, a cadmium telluride solar component is laminated and installed in a junction box; S2 is short-circuited with the positive and negative terminals of the battery of the cadmium telluride solar component; S3 irradiates cadmium telluride solar modules with white laser irradiation modules. The method for improving the stability of a cadmium telluride battery of the present invention prevents copper ions from diffusing into the window layer, reduces short circuits and internal defects of the battery caused by the diffusion of copper ions, and enhances the stability and life of the battery.
Description
technical field [0001] The invention relates to the field of cadmium telluride batteries, in particular to a method for improving the stability of cadmium telluride batteries. Background technique [0002] Under normal circumstances, under the influence of major external factors (such as dust, stains, etc.), solar cell modules are tested under the same standard environment. Generally, the attenuation of solar cell modules is relatively slow in the first 10 years, and the 10th year is about 93% of the initial power. %, the decay accelerates in 10-20 years, about 82% of the initial power in the 20th year, the decay becomes slow in the 20th-25th year, about 80% of the initial power in the 25th year, and the decay is very small in 25-30 years, Basically stable at about 78%-80% of the initial power, we can call it the aging decay of the component, that is, the very slow power drop in long-term use, the main reason is related to the slow decay of the battery, which is also related...
