Abstract

CuInS₂-based bulk heterojunction (BHJ) film is a promising photoelectric conversion material system for photovoltaics. Here, a dopant-free polymer PTB7-Th is used as a hole transport material (HTM) in CuInS₂-BHJ solar cells for the first time. The morphology, optical property and electrical property of the PTB7-Th film are investigated. The CuInS₂-BHJ solar cell using PTB7-Th as a HTM achieves a considerable power conversion efficiency of 8.66% and exhibits a good stability in ambient condition.
