Abstract Perovskite Solar Cells (PSCs) have attracted much interest as a high-efficiency nanoscale solar cells. The PSCs consist of organic-inorganic halide perovskite (CH3NH3PbI3) sensitizer, hole transport materials (HTMs), electron transport materials, and electrodes. Among them, HTM plays a key role in the performance of the device. Organic materials such as Spiro-OMeTAD have been mainly used as HTM, but most of them are expensive. As an alternative, there have been efforts to develop more economical HTM materials, and CuSCN is one of the promising materials for HTM. In fact, PSCs employing the CuSCN HTM was reported and exhibited the power conversion efficiency larger than 17 %. In this presentation, we investigated the dynamics of charge carriers in PSCs employing CuSCN HTM by using time-resolved spectroscopies. In particular, by applying time-resolved photoluminescence (TR-PL) and transient absorption (TA) spectroscopies to CuSCN-based PSCs, we observed the dynamics of charge injection and charge recombination on nanosecond timescales.
