研究目的
To design and fabricate a sandwiched methyl ammonium lead iodide (CH3NH3PbI3) based Perovskite Solar Cell (PSC) using PEDOT: PSS as hole transport material (HTM) in room ambient condition, achieving high efficiency and stability.
研究成果
The study successfully fabricated a solution-processed perovskite solar cell using PEDOT: PSS as HTM, achieving a high efficiency of 15.24% under 1 sun condition in ambient air. The cell demonstrated stability for two hours, highlighting the potential of PEDOT: PSS in enhancing PSC performance. Future research should focus on improving stability for longer durations.
研究不足
The stability of the cell in ambient air is limited to approximately two hours, which is a significant constraint for commercialization.
