In the past few years, organic-inorganic halide perovskite solar cells have been attracted much attention due to their rapidly increasing power conversion efficiencies and compatibility with low cost fabrication. High performance achieved in perovskite solar cells has been attributed to high absorption coefficient and high mobilities for both electrons and holes. Surfaces and interfaces in these solar cell devices can have a strong impact on device performance. Also, many of the pressing challenges (e.g., stability, hysteresis, etc.) in organometal halide perovskite solar cell research are closely correlated with surfaces and interfaces. My group at OIST investigates relevant surfaces and interfaces for better understanding about perovskite materials and solar cells. Based on the findings, we develop strategies to further improve device performance. By creating a connection between surface and interface science studies and device fabrication and characterization, we have obtained deepened understanding about perovskite solar cells. In this presentation, I will introduce our recent research findings.
