Research Update: Overview of progress about efficiency and stability on perovskite solar cells

Abstract

Due to the high conversion efficiency, organic-inorganic hybrid perovskite (CH3NH3PbI3) solar cells are investigated for new practical energy resources for our future society. However, the perovskite solar cells have been quite unstable devices. In this manuscript, the history of perovskite solar cells is introduced, and then, the efforts to improve and understand the stability issue of perovskite solar cells are summarized.
