What other materials do monocrystalline silicon solar cells contain silicon?

Cut the monocrystalline silicon rod into slices, usually about 0.3mm thick. Silicon wafers undergo polishing, cleaning and other processes to become raw silicon wafers for processing. To process solar cells, the silicon wafer must first be doped and diffused. Generally, dopants are traces of boron, phosphorus, antimony, etc. Diffusion is carried out in a high temperature diffusion furnace made of quartz tubes. In this way, a PN junction is formed on the silicon chip. Then, the screen printing method is used to print the finely prepared silver paste onto the silicon wafer to create grid lines. After sintering, the back electrode is made at the same time, and an anti-reflection source is covered on the surface with the grid. Lines to prevent a large number of photons reflected from the smooth surface of the silicon wafer.Therefore, monocrystalline silicon solar cells are produced. After random inspection, the monomers can be assembled into solar cell modules (solar panels) according to the required specifications, and a certain output voltage and current can be formed by series and parallel connection. Finally, it is encapsulated with frames and materials. I hope this will help you. Add: Monocrystalline silicon solar cells are composed of the following parts: white glass, silicon crystal plate, TPT backsheet and EVA film. The middle layer is a silicon crystal plate, which is also the main component. Top To convert light energy into electrical energy, the upper layer is ultra-white glass and the lower layer is TPT backplane. These three layers are bonded together by an EVA adhesive film. After bonding, apply EVA solar sealant. The roleof the film is very critical. It requires high light transmittance, high peel strength, appropriate cross-linking degree and excellent aging resistance. Shanghai Tianyang EVA film has high technology content and is good to use when the EVA is ethylene polyvinyl acetate. .

A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since there are no moving parts, it can operate for a long time without any wear and tear. Simple photovoltaic cells can power watches and computers, while more complex photovoltaic systems can light homes and power the grid. Photovoltaic panel modules can take different shapes andModules can be connected to generate more electricity. In recent years, photovoltaic panel components have been used on roofs and building surfaces, and are even used in windows, skylights or protective devices. These photovoltaic installations are often called building-mounted photovoltaic systems.
