Solar Cell Production Line

Cleaning & Texturing: Wafers are cleaned with industrial soaps and form square-based pyramids also called texture. The texturization helps to reduce the reflection of sunlight. 

Diffusion: Wafers that have been pre-droped with boron during the casting process are then given a negative(n-type) surface characteristic by diffusing them with a phosphorus source at high temperature, which in turn creats the negative/positive(n-p) junction.

Etching: Phosphorus diffuses not only into the desired wafer surface but also into the side and the opposite surface to form PN. This gives a shunt path between the cell front and rear. Removal of the path around the wafer edge/edge junction isolation is named etching.

PECVD: By PECVD equipment, the wafers are coated with anti-reflection coating(ARC). It's the blue silicion nitride film to reduce reflection and promote absorption of light.

Printing & Heating: it was adopted by printing paste with screen technology to print the electrodes of silicion solar, and form a good ohmic contact.

Testing & Sorting: It means classifying the cells according to their efficiency tested under the simulated sunlight.
