We have previously reported that phosphine (PH3) surface treatment of a p-type crystalline germanium (c-Ge) substrate improves the c-Ge heterojunction solar cell performance. In this study, the effects of the heterointerface properties of the c-Ge heterojunction solar cell were investigated. We found that the deposition temperature of the heterojunction layer and O2 surface treatment before the PH3 surface treatment influence the interface phase structure and band structure. Consequently, a conversion efficiency of 7.61% with a high open-circuit voltage of 0.270 V was obtained.
