为什么铅甲基铵三碘化钙钛矿基太阳能电池需要介孔电子传输支架（但不一定是空穴导体）
Why Lead Methylammonium tri-IODIDE perovskite-based solar cells requires a mesoporous electron transporting scaffold (but not necessarily a hole conductor)
摘要：
采用电子束感应电流（EBIC）对CH 3 NH3 PbI 3基太阳能电池进行了表征，并与CH 3 NH3 PbI 3-xClx基太阳能电池进行了比较。工作电池中的电荷分离效率的空间图示出了两种薄膜电池的p-i-n结构。有效扩散长度，LD，（从EBIC曲线）表明，空穴提取显着更有效地比电子在CH 3 NH3 PbI 3，解释了为什么CH 3 NH3 PbI 3为基础的电池需要介孔电子导体，而CH 3 NH3 PbI 3-xClx的，其中LD值是可比的两种电荷类型，不。
英文摘要：
CH3NH3PbI3-based solar cells were characterized with electron beam-induced current (EBIC), and compared to CH3NH3PbI3-xClx ones. A spatial map of charge separation efficiency in working cells shows p-i-n structures for both thin film cells. Effective diffusion lengths, LD, (from EBIC profile) show that holes are extracted significantly more efficiently than electrons in CH3NH3PbI3, explaining why CH3NH3PbI3-based cells require mesoporous electron conductors, while CH3NH3PbI3-xClx ones, where LD values are comparable for both charge types, do not.
