Problems solved by technology

[0002] At present, the well-known solar photoelectric conversion depends on the silicon wafer in the solar cell module, which has a good light absorption effect. With the continuous improvement of solar cell modules, the photoelectric conversion rate of the silicon wafer in the solar cell module is in the The current production level has reached the limit, and it has become a difficult problem to improve the photoelectric conversion rate of solar cells
At the same time, because the workplaces of solar cells are mostly set up outdoors or in deserts with harsh environments, the surface of solar cell modules is easy to get dirty, and it is difficult to clean after being dirty.
