Abstract

Solar cell architectures with excellent surface passivation that use commercially available multi-milliseconds lifetime wafers can potentially benefit from using higher bulk resistivities. In this study, final device results of the silicon heterojunction (SHJ) cells manufactured on very high bulk resistivity (1k Ωcm) wafers are presented. They are shown to have high performance comparable to the commercial bulk resistivity wafers at standard testing conditions (STC) as well as different illumination conditions. In addition, the cells with high resistivity wafers are shown to be more reliable than standard bulk resistivity with higher breakdown voltages.
