ABSTRACT: In the past few years,organometalhalideperovskitesolar cells have become a topic under intensive investigation. The power conversion efficiency of these solar cells is rapidly rising with a record exceeding 22%,which is on par with the best single crystalline silicon solar cells. For efficient stable solar cells, surfaces and interfaces are of paramount importance. My group at OIST is making concerted efforts to investigate relevant surfaces and interfaces for better understanding aboutperovskitematerials and solar cells. In this talk, I will introduce our research progress on real-space atomic-scale imaging of organic-inorganic hybridperovskite[1],perovskitesolar cell stability and lifetime under operation conditions [2-7], and the vapor-based methods that can be used to fabricate semi-transparent high efficiencyperovskitesolar cells [8-12].
