Introduction of Monocrystalline Solar Panel/Solar Cell
2022-08-18
Among the silicon series solar cells, monocrystalline silicon large solar cells have the highest conversion efficiency and the most mature technology. High-performance monocrystalline silicon cells are based on high-quality monocrystalline silicon materials and related thermal processing techniques.
Now the electric technology of single crystal silicon is nearly mature. In the production of batteries, technologies such as surface texture, passivation of the emitter region, and partition doping are generally used. The developed batteries mainly include planar single crystal silicon batteries and grooved buried batteries Gate electrode monocrystalline silicon cells.
The improvement of the conversion efficiency mainly depends on the surface microstructure treatment of single crystal silicon and the subregional doping process. The surface of the cell is textured by photolithography to make an inverted pyramid structure. And put a 13nm on the surface. A thick oxide passivation layer is combined with two anti-reflection coatings. The ratio of the width and height of the grid is increased by the improved electroplating process: the conversion efficiency of the cell obtained by the above is more than 23%, and the maximum value can reach 23.3%.
