报告内容摘要：

Metal halide perovskite materials and devices have become one of the most active research fields and 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 devices. Instability, upscalability and lead toxicity are currently the major challenges for perovskite photovoltaic technology to move forward towards commercialization. In this talk, I will present our research progress on degradation mechanisms of perovskite materials], development of strategies to improve perovskite solar cell device stability, reduction of lead leakage using self-healing polymer-based encapsulation, upscalable fabrication of perovskite solar cells and modules, and surface science understanding of perovskite materials and stability.
