PERC-like contact for CdTe Solar Cells
Project ID: D2019-40BackgroundCdCl2 activation is a well-known method to passivate grain boundaries for CdTe solar cells. In crystalline silicon solar cells, manufacturers have started to modify film structures to incorporate a passivated layer. These are called Passivated Emitter and Rear Cells (PERC). The additional layer decreases the recombination...
