DEK Solar and the Institute for Solar Energy Research Hamelin (ISFH) have worked in partnership to increase industrial silicon solar cells' (in this case, Passivated Emitter and Rear Cell, or PERC) conversion efficiency to a record 21.2% using screen-printed metal contacts on the cell rear side and a screen/stencil dual print process on the cell front side. Typically, screen-printed solar cell efficiency ranges from 17.5% to 19.5%, but this latest development sets a new world record for PERC ...This story is related to the following:Computer Hardware and PeripheralsScreen Printing Equipment & Supplies | Solar Cell Metallization
