LFC Laser Fired Contacts PE-W700-D Laser Welding Machine
Description
To get high efficiency Si Solar cells, reduction of surface recombination losses and good surface passivation and/or Bach Surface Field (BSF) formation are needed. LFC is a technique developed to form the point or line contact pattern of solar cells with dielectric rear passivation.
Specifications
| Product Type | PE-W700-E |
| Scanning Speed | 10,000 contacts/s |
| Contact Depth | 0.5-4μm |
| Wafer Size | 125mm x 125 mm, 156mm x 156mm |
Application
The technique utilizes laser ablation of silicon oxide or silicon nitride deposited on top of a film of aluminum metal,
to achieve a low series resistance ohmic contact. Due to the back of the battery with the structure of the point
contact, the metal composite greatly reduced, a substantial increase in performance on the back of the battery
passivation. The back of the battery technology to solve the traditional high complex defects.
