Organic-inorganic hybrid perovskite solar cells have attracted much attention as one of the most promising next generation photovoltaic technologies. For efficient stable solar cells, interfaces are of paramount importance. My group at OIST is making efforts to obtain better understanding about interfaces in perovskite solar cells. In this talk, I will present our recent research findings regarding interface engineering, which provides a viable route to the fabrication of perovskite solar cells with high efficiency and improved stability [1, 2].
