THRESHOLD ADJUSTMENT IMPLANTS FOR REDUCING SURFACE RECOMBINATION IN SOLAR CELLS |
摘要 |
Embodiments of the invention relate to methods of forming solar cell devices to reduce recombination losses and solar cell devices made by such methods, for example back contact solar cells, such as emitter-wrap-through (EWT) solar cells. The methods may include disposing an amount of impurities into a charge compensating region formed on a rear surface of a substrate and forming a rear surface passivation layer over at least a portion of the charge compensating region, wherein the amount of the impurities disposed in the charge compensating region is selected to compensate for an amount of charge formed in the rear surface passivation layer. |
