Features:

Monocrystalline silicon solar cell is currently the fastest developed solar cell, its composition and production process
The art has been finalized, and the products have been widely used in space and ground facilities. This solar cell uses high-purity monocrystalline silicon
The rod is the raw material, and the purity is required to be 99.999%. In order to reduce production costs, solar cells used on the ground are now
Using solar-grade monocrystalline silicon rods, material performance indicators have been relaxed. Some can also use semiconductor device processing
The head and tail materials and waste monocrystalline silicon materials are redrawn into monocrystalline silicon rods for solar cells. Monocrystalline silicon
The rod is cut into slices, generally about 0.3 mm thick. After the silicon wafer is formed, polished, cleaned, etc., it is made to be processed
Raw silicon wafers. To process solar cells, first doping and diffusion on the silicon wafers. Generally, the dopants are trace amounts.
Of boron, phosphorus, antimony and so on. Diffusion is carried out in a high-temperature diffusion furnace made of quartz tubes. This is formed on the silicon wafer
PN junction. Then use the screen printing method to print the prepared silver paste on the silicon wafer and make grid lines on it. After sintering, at the same time
The back electrode is made, and an anti-reflection source is coated on the surface with the grid lines to prevent a large number of photons from being reflected by the smooth surface of the silicon wafer.
Shoot off, and at this point, the monolithic wafers of the monocrystalline silicon solar cell are made. After the single chip has been spot-checked and inspected, you can press
The required specifications are assembled into solar cell modules (solar panels), which are constructed in series and parallel
One-definite output voltage and current, and finally encapsulated with frame and packaging materials.
