Multi-crystalline Cells |
| 156mmx156mm Multicrystalline Solar PV Cells |
|
|
Power Liners multicrystalline solar cells are manufactured from highly purified polysilicon in a state-of-the-art manufacturing plant that permits use of thin silicon wafers. The wafers are handled through non-contact Bernoulli grippers and moved horizontally on conveyor belts and rollers through various process steps resulting in stress-free cell.
The cells are coated with silicon nitride (SiNx:H) anti-reflection layer using DVD sputtering to have uniform deposition ensuring maximum light capturing capability throughout their lifetime. |
