介孔钙钛矿太阳能电池中二氧化锡基电子传输层的合理设计:比传统双层结构更具动力学优势(英文)
Rational design of SnO2-based electron transport layer in mesoscopic perovskite solar cells:more kinetically favorable than traditional double-layer architecture
【摘要】 本文采用点分布SnO2和TiO2介孔层中的纳米粒子组成的"协同层"作为高效介孔钙钛矿太阳能电池的电子传输层衬层.基于该新策略,电荷复合和能量损失路径被有效阻隔,使得之前报道的SnO2基电子传输层介孔钙钛矿太阳能电池中的强烈电荷复合被有效抑制.同时,整个介孔钙钛矿太阳能电池的串联电阻显著降低.新型的电子传输层动力学上更有利的电子传输有效提升了介孔钙钛矿太阳能电池的光伏性能,并明显抑制了电池的回滞.
【Abstract】 Here,the interfacial synergism of discontinuous spot shaped SnO2 and TiO2 mesoporous nanocomposite as electron transfer layer(ETL) underlayer is presented in highly efficient mesoscopic perovskite solar cells(M-PSCs). Based on this new strategy,strong charge recombination observed in previous SnO2-based ETLs is suppressed to a great extent as the pathways of charge recombination and energy loss are blocked effectively. Meanwhile,the internal series resistance of entire M-PSC is decreased remarkably. The new ETL is more kinetically favorable to electron transfer and thus results in significant photovoltaic improvement and alleviated hysteresis effect of M-PSCs.
