Abstract

Abstract : Sodium (Na) has been identified as a benign contaminant in some thin film solar cells. Abstract : Sodium (Na) has been identified as a benign contaminant in some thin film solar cells. Here, we have studied the impact of sodium on the properties of CdS/Sb2 Se3 superstrate thin film solar cells. NaF deposited at the CdS/Sb2 Se3 heterojunction severely degraded the device performance, yet NaF introduced into the Sb2 Se3 film after the completion of the heterojunction showed a negligible influence on the film conductivity and device performance. We concluded that sodium could easily diffuse into the Sb2 Se3 film and probably locates in the gap between (Sb4 Se6 ) n ribbons, being inert in Sb2 Se3 solar cells.
