摘要
采用热蒸发法沉积无毒、稳定、价廉的无机氧化物Mo O_3,将其作为钙钛矿电池的阳极缓冲层。结果表明,Mo O_3阳极缓冲层的引入有利于增强光吸收层到阳极的空穴提取效率,使电池的短路电流密度(J_(sc))和填充因子(FF)均有较大幅度提高,取得了9.96%的平均光电转换效率(PCE)。此外,实验发现,Mo O_3阳极缓冲层可以阻挡酸性的PEDOT∶PSS对ITO的腐蚀,有利于增强电池的稳定性。
The inorganic oxide MoO 3 thin films were prepared by thermal evaporation deposition method,and used as an anode buffer layer for PHJ perovskite solar cells.The results show that the MoO 3 anode buffer layer can enhance the hole extraction efficiency from the light absorption layer to the anode,and benefit the improvement of the short-circuit current(J sc)density and the fill factor(FF)of the solar cells.An average power conversion efficiency(PCE)of 9.96%is achieved finally for the solar cells with a MoO 3 anode buffer layer.In addition,the results also show that the MoO 3 anode buffer layer can hinder the corrosion of ITO by acidic PEDOT∶PSS and improve the stability of the solar cells.
