【Product description】
1. Type : Monocrystalline Solar Cell(210mm X 210mm, Full square)
2. solar cell technology
Laser SE combined with PERC technology is used to make this family high power solar cell. PREC is short for Passivated Emitter and Rear Cell. It is based on the P type monocrystalline silicon solar cell.
PERC cell technology defines a solar cell architecture that differs from the standard cell architecture that has been in use for three decades and that is usually featured in all photovoltaic manuals.
3. Power of 210mm solar cell
132pcs half-cut high power 210mm Mono PERC solar cells can assembly solar panels with power up to 665 watt. It is beneficial for lowering the BOS cost of solar power system.
【Process flow】
【Key features】
Double side generation
