What Are Monocrystalline Solar Panel Cells?

Among the silicon series solar panels, monocrystalline solar panel cells have the highest conversion efficiency and the most mature technology. High-performance monocrystalline solar panel cells are based on high-quality monocrystalline silicon material and related thermal processing techniques.


1. Introduction of monocrystalline solar panel cells


Monocrystalline silicon refers to the overall crystallization of silicon material into a single crystal form and is currently a commonly used photovoltaic power generation material. Monocrystalline solar panel cells are the most mature technology in silicon-based solar cells and have the highest photoelectric conversion efficiency compared to polycrystalline silicon and amorphous silicon solar panels. Monocrystalline solar panel cells, which are solar panels made of high-purity monocrystalline silicon rods, are the fastest developing solar cells. Its structure and production process have been finalized, and the products have been widely used in space and ground. Solar cells mainly include crystalline silicon cells and thin film cells, and their respective characteristics determine their irreplaceable status in different applications.


Now the process of monocrystalline solar panel cells is nearly mature. In the production of batteries, technologies such as surface texture, passivation of the emission region, and partition doping are generally used. The developed batteries mainly include flat monocrystalline solar panel cells and grooved buried gate electrode monocrystalline solar panel 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 solar panel 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 solar panel produced by the above is more than 23%, and the maximum value can reach 23.3%.


2. Advantages of monocrystalline solar panel cells


At present, the photoelectric conversion efficiency of monocrystalline solar panel cells is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency among all types of solar panels. Since monocrystalline silicon is generally encapsulated by tempered glass and waterproof resin, it is strong and durable, and its service life is generally up to 15 years, up to 25 years.


The conversion efficiency of monocrystalline solar panel cells is undoubtedly the highest and still dominates in large-scale applications and industrial production. Although its conversion efficiency is high, in order to save high-quality materials, looking for alternative products for monocrystalline solar panel cells, thin-film solar cells are now developed, among which polycrystalline silicon thin-film solar panels and amorphous silicon thin-film solar panels are typical representatives.
