【Product description】
Bifacial PREC is short for bafacial Passivated Emitter and Rear Cell. It is based on the P type monocrystalline silicon solar wafer.
For more generation in the same footprint, PERC has been naturally upgraded to bifacial PERC.
On this basis, bifacial PERC is also becoming an important route in the development of the technology. The commonly used manufacturing technology for bifacial PERC cell is to change the printing process of the PERC single-sided cell, and changing the rear surface from whole aluminum layer to a local aluminum layer. This allows incidental light on the rear surface to enter the cell from the exposed layer and create photoelectric conversion on both the front and rear sides.
