Perovskite solar cell with low cost Cu-phthalocyanine as hole transporting material

摘要

Low cost copper phthalocyanine has been used as hole-transporting material for the construction of organolead halide solid state perovskite solar cells. The cells were assembled and tested under ambient conditions. They achieved a power conversion efficiency of 5.0% using copper phthalocyanine, which appears to have potential to replace the currently used organic hole transporters. The present work has also examined the possibility of upscaling by construction of small cell modules.
