Role of Morphology and Crystallinity of Nanorod and Planar Electron Transport Layers on the Performance and Long Term Durability of Perovskite Solar Cells

High efficiency is routinely reported in CH3NH3PbI3−xClx sensitized mesoscopic solar cells (PSCs) employing planar and scaffold architectures; however, a systematic comparison of their photovoltaic performance under similar experimental conditions and their long term stability have so far not been d...
