Abstract
Solar cells based on the perovskite-structured light absorber CH3NH3PbI3 have recently emerged at the forefront of solution-processable photovoltaic devices, with power conversion efficiencies as high as 20.1% having now been certified. In this presentation, I will discuss our research group’s work in the area of perovskite solar cells. Our early work demonstrated that room temperature solution-processing techniques can be used to prepare devices on flexible substrates while retaining excellent power conversion efficiencies. Since then, we have examined issues related to charge carrier diffusion, interfacial contacts, and device flexibility, with our most recent efforts focusing on probing device failure mechanisms using in situ synchrotron-based techniques.
