Abstract

Here we report a solution processed environmentally friendly MoS₃ hole-transport material for Sb₂Se₃ solar cells, where MoS₃ exhibits a matched energy level relative to Sb₂Se₃. In the synthesis, H₂S produced by the thermal decomposition of (NH₄)₂MoS₄ is found to efficiently eliminate the antimony oxide impurity formed on the Sb₂Se₃ surface. Finally, the all-inorganic Sb₂Se₃ solar cell delivers an efficiency of 6.86% with excellent stability.
