ResumoPerovskite solar cells (PSCs) are currently under both of intense academic and industrial investigations. Here, two dimethoxyphenylamine-substituted carbazole derivatives (SYN1 and PARA1), as hole-transporting materials (HTMs) for PSCs, have been synthesized via two-step synthesis with low cost and simple operation. PSCs devices based on SYN1 and PARA1 showed power conversion efficiencies (PCE) of 11.4% and 13.1%, respectively, outperforming that of Spiro-OMeTAD (12.0%), demonstrating the dimethoxyphenylamine-substituted carbazole derivatives are good candidates as HTMs for perovskite solar cells. Time-resolved photoluminescence (TRPL) and J-V test under dark indicate that the hole injecting efficiency and dark current affect the cell performance seriously.
