Multibusbar, Laser SE and PERC technology are used to make this family high power solar cell. Multibusbar is featured with shorter and narrower grid fingers which result in a higher fill factor and a higher current.
At the same time Multibusbar technology can lower costs: Up to 25 % silver can be saved when screenprinting the cells. Moreover, light hitting the round copper wires is reflected back onto the cell.
This very efficient light recycling contributes to the minimized cell-to-module (CTM) loss. Bifacial 166mm PREC is short for bafacial 166mm Passivated Emitter and Rear Cell. It is based on the P type monocrystalline silicon solar wafer. For more generation, 156.75mm PERC has been naturally upgraded to bifacial 166mm PERC.
