Description

technical field [0001] The invention relates to a solar photoelectric conversion glass, in particular to a solar photoelectric effect glass that can be applied to solar cells. Background technique [0002] At present, the known photoelectric conversion of solar energy depends on the silicon wafer in the solar cell module, which has a good light absorption effect. With the continuous improvement of the solar cell module, the photoelectric conversion efficiency of the silicon wafer in the solar cell module The current manufacturing level has reached the limit, and it has become a difficult problem to improve the photoelectric conversion efficiency of solar cells. At the same time, since the workplaces of solar cells are mostly installed outdoors in harsh environments, the surface of solar cell modules is easily dirty, and it is difficult to clean after being dirty. One of the methods we know to solve the photoelectric conversion efficiency of solar cells is to increase the li...

Problems solved by technology

Ordinary glass is difficult to do because of its high iron content, which cannot meet the performance requirements as a glass substrate for solar cells; people try to use an ordinary ultra-clear glass, which has a low iron content, but it is Produced by the float process, the surface is smooth and clean, and has the disadvantage of high reflectivity, which has certain shortcomings as a solar cell glass substrate; there is also an ordinary ultra-clear glass, which is produced by the rolling process. The disadvantage is that light is not transparent, and it is also disadvantageous for solar cell glass substrates

At present, the best performance is an ultra-white glass with evenly distributed dot patterns on the surface. It has low iron content and good refraction, but its self-cleaning performance is poor.

In addition to the above-mentioned defects, the above-mentioned several glass substrates all have the problem of being difficult to clean
