Product Description
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-doped 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 creates 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 an anti-reflection coating (ARC). It's the blue silicon nitride film that reduces reflection and promotes the absorption of light.
Printing & Heating: It was adopted by printing paste with screen technology to print the electrodes of silicon solar, forming a good ohmic contact.
Testing & Sorting: It involves classifying the cells according to their efficiency tested under simulated sunlight.
