摘要:
采用旋涂法,在二氧化锡(SnO2)与钙钛矿层间引入1-金刚烷胺盐酸盐(ADA)作为界面改性剂,形成电子回流阻挡层,起到钝化界面缺陷、阻挡电子回流和抑制界面非辐射复合的作用,并能提升钙钛矿太阳能电池的光电性能。结果表明:ADA中氨基孤对电子可与未配位Pb2+配位,有利于形成高质量的钙钛矿薄膜,降低缺陷密度,提升开路电压;经过ADA改性的最佳钙钛矿太阳能电池功率转换效率(PCE)达到了23.07%,开路电压为1.13 V,短路电流密度为24.67 mA·cm-2,填充因子为82.59%;改性器件在空气环境中存放1 000 h后,PCE仍保持85%以上,效率和稳定性均显著增强。
Abstract:
Using the spin-coating method, 1-amantadine hydrochloride(ADA)was introduced as an interface modifier between tin dioxide(SnO2)and perovskite layers to form an electron reflow barrier layer, which served to passivate interface defects, prevent electron reflow, and suppress non-radiative recombination at the interface, and could also enhance the photoelectric performance of perovskite solar cells. The results showed that the amino lone pair electrons in ADA could coordinate with uncoordinated Pb2+, which was conducive to the formation of high-quality perovskite films, reducing defect density and increasing open-circuit voltage. The optimal power conversion efficiency(PCE)of the perovskite solar cells modified by ADA reached 23.07%, theopen-circuit voltage was 1.13 V, the short-circuit current density was 24.67 mA·cm-2, and the fill factor was 82.59%. After being stored in an air environment for 1 000 h, the modified device still maintained a PCE of over 85%, and both efficiency and stability were significantly enhanced.
