Efficient modification of the interface between metal cathode and electron transport layer are critical for achieving high performance and stability of the inverted perovskite solar cells (PSCs). Herein, a new alcohol-soluble rhodamine-functionalized dodecahydro-closo-dodecaborate derivate, RBH, is developed and applied as an efficient cathode interlayer to overcome the (6,6)-phenyl-C61 butyrie acid methyl ester (PCBM)/Ag interface issues. By introducing RBH cathode interlayer, the functions of the interface traps passivation, interfacial hydrophobicity enhancement, interface contact improvement as well as built-in potential enhancement are realized at the same time and thus correspondingly improve the device performance and stability. Consequently, a power conversion efficiency (PCE) of 21.08% and high fill factor of 83.37% are achieved, which is one of the highest values based on solution-processed MAPbI3/PCBM heterojunction PSCs. Moreover, RBH can act as a shielding layer to slow down moisture erosion and self-corrosion. The PCE of the RBH devices still maintain 84% for 456 h (85 °C @ N2), 87% for 360 h (23 °C @ relative humidity (RH) 35%) of its initial PCE value, while the control device can only maintain ≈23%, 58% of its initial PCE value under the same exposure conditions, respectively.

通过罗丹明功能化十二氢-邻十二硼酸盐衍生物中间层克服倒置钙钛矿太阳能电池中的 PCBM/Ag 界面问题
金属阴极和电子传输层之间界面的有效修饰对于实现倒置钙钛矿太阳能电池(PSC)的高性能和稳定性至关重要。在此,开发了一种新的醇溶性罗丹明功能化十二氢-近-十二硼酸酯衍生物RBH,并将其用作有效的阴极中间层,以克服(6,6)-苯基-C 61丁酸甲酯 (PCBM)/Ag 界面问题。通过引入RBH阴极中间层,同时实现了界面陷阱钝化、界面疏水性增强、界面接触改善以及内建电位增强的功能,从而相应提高了器件的性能和稳定性。因此,实现了 21.08% 的功率转换效率 (PCE) 和 83.37% 的高填充因子,这是基于溶液处理的 MAPbI 3 /PCBM 异质结PSC的最高值之一。此外,RBH可以充当屏蔽层,减缓水分侵蚀和自腐蚀。RBH器件的PCE在456小时内仍保持84%(85°C @ N 2),360小时(23℃@相对湿度(RH)35%)时其初始PCE值的87%,而控制装置在相同暴露条件下只能维持其初始PCE值的约23%、58%,分别。
