P Type Monocrystalline Silicon Solar Cell
【Product description】
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.
PERC has been upgraded to the PERC+ level. Examples for PERC+ are bifacial PERC, black silicon texturing and a PERCT structure.
PERC is high on the hit list of record efficiencies. In the last 12 months, the world record was broken 6 times. Today’s highest efficiency PERC cell of 23.95% was made by one of the China solar PV leaders, followed by a 23.6% cell from another China solar PV leader.
【Process flow】
PERC and BiPERC(Bifacial PERC) process flow shows in the following picture:
【Key features】
Higher output power
Excellent low-light performance
Lower temperature coefficient
