Raw material processing
Silicon material
Silicon ingot
silicon wafer
Solar cell production process
Silicon Chip Selecting
Inspection by the naked eye and scratch.
Texturing
We carry out an anti reflection film so that it does not reflect the incident light on the surface of the cell that absorbs light efficiently. In order to increase the surface area of the cell, and increase the photoelectric conversion efficiency of the cell.
Diffusion
With a silicon wafer phosphorus by diffusion, by creating a N layer will form the photoelectric conversion of the underlying structure of PN junction.
Etching
After spreading, a short circuit ring is formed around the silicon wafer.
PECVD
In order to reduce the reflection on the surface of the main solar cells to form a film.
Screen Printing
The electrode pattern is printed on the backside of the silicon substrate by a screen printing method.
Flash Test
Automatically select output from each unit.
