摘要

采用热蒸发法沉积无毒、稳定、价廉的无机氧化物MoO

，将其作为钙钛矿电池的阳极缓冲层。结果表明，MoO

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（

）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，MoO

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。

Abstract

The inorganic oxide MoO

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

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 (

) 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

anode buffer layer. In addition

the results also show that the MoO

anode buffer layer can hinder the corrosion of ITO by acidic PEDOT:PSS and improve the stability of the solar cells.
