Perovskite Material and Solar Cell Research by Surface Science and Advanced Characterization

Perovskite solar cell research continues to progress rapidly on various fronts. My group at OIST is making efforts to use surface science and advanced material characterization to obtain in-depth understanding about perovskite materials and solar cells. Instability and upscalability are currently the major challenges for perovskite photovoltaic technology to move forward towards commercialization [1]. In this talk, I will present our research progress on degradation mechanisms of perovskite materials [2], development of strategies to improve perovskite solar cell device stability [3], upscalable fabrication of perovskite solar cells and modules [4], and surface science understanding of perovskite materials and stability [5].
