研究目的
Investigating the electrochemical deposition of CuSCN thin film for use as a hole transport material in inverted planar perovskite solar cells.
研究成果
The electrochemical deposition of CuSCN at -0.350V is favorable for developing appropriate thickness for high performance perovskite solar cells, achieving a conversion efficiency of 3.5%.
研究不足
The study focuses on the preliminary results of using CuSCN as HTM in perovskite solar cells, indicating potential for optimization in deposition parameters and thickness control for higher performance.
