摘要:
为了降低电子传输层 (Electron transport layer，ETL) 与钙钛矿层之间的界面缺陷态密度，通过旋涂法在氧化铟锡（Indium tin oxide，ITO）透明导电玻璃上制备一层SnO2电子传输层，并在其上表面旋涂(NH4)2S以修饰SnO2和钙钛矿光吸收层之间的界面。通过X射线光电子能谱、扫描电子显微镜、电化学阻抗谱等表征手段分析(NH4)2S修饰对钙钛矿太阳能电池（Perovskite solar cells，PSCs）光电性能的影响。结果表明：NH4＋降低了SnO2的表面羟基(—OH)缺陷态密度，增强了界面的疏水性，减少了钙钛矿的形核位点，增大了钙钛矿晶粒；S2-填补了SnO2表面的氧空位(OV) ,同时部分S2-还与未配位Pb+连接减少界面处Pb缺陷，抑制了界面处载流子复合；经过(NH4)2S的修饰，PSCs开路电压从1.07V提高到1.11V，光电转化效率达到了20.53%。(NH4)2S修饰后的PSCs具有更高的光电转化效率、更好的长期稳定性。该研究可为PSCs商业化提供新的思路。
