By the introduction of an organic silane self-assembled monolayer, an interface-engineering approach is demonstrated for hole-conductor-free, fully printable mesoscopic perovskite solar cells based on a carbon counter electrode. The self-assembled silane monolayer is incorporated between the TiO2 and CH3NH3PbI3, resulting in optimized interface band alignments and enhanced charge lifetime. The average power conversion efficiency is improved from 9.6% to 11.7%, with a highest efficiency of 12.7%, for this low-cost perovskite solar cell.

具有有机硅烷自组装单层的完全可印刷介观钙钛矿太阳能电池

通过引入有机硅烷自组装单层，展示了一种基于碳对电极的无空穴导体、完全可印刷的介观钙钛矿太阳能电池的界面工程方法。自组装硅烷单层结合在 TiO2 和 CH3NH3PbI3 之间，从而优化了界面能带排列并延长了电荷寿命。这种低成本钙钛矿太阳能电池的平均功率转换效率从 9.6% 提高到 11.7%，最高效率为 12.7%。
