Mono Solar Cell Monocrystalline Solar Cell Monocrystalline Solar Cell 156x156

Product Introductionvery high quality monocrystalline silicon solar cells 156x156mm
Our company Benya Technology is running a modernized auotomatic production line for high quality mono solar cell. All our mono solar cells are made by high-end precision equipments accurately to make sure every cell we sold to clients is in the best quality and can be used to make high efficiency mono solar panels. We now make 4BB mono solar cells but will updated to 5BB in near future.Physical CharacterDiemnsion:156mmx156mm±0.5mmDiagonal:220mm±0.5mmThickness (Si):200±20 μmFront (-):blue anti-reflecting coating (silicon nitride)

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.
