Problems solved by technology

[0003]With the current technical level, it is difficult to significantly improve the power generation efficiency of crystalline silicon by thinning or coating on crystalline silicon materials
As a cover material for crystalline silicon cells, high transmittance glass for solar cells, also known as ultra-white embossed glass, formula design with low iron content (absorption rate is less than 0.5%) and textured surface treatment, its The transmittance of its own reaches about 91.5%, which has reached the limit from the material itself, which affects the power generation efficiency of solar cells
