PERovskite deFECTs: Physics, eVolution and Stability

点击翻译按钮获取中文摘要

Defects in metal halide perovskites for photovoltaics are a topic of intense interest and scrutiny. While metal halide perovskites are generally categorized as ‘defect tolerant’, significant efforts are dedicated to suppressing defects in perovskite materials in order to improve the photovoltaic efficiency and stability of perovskite solar cells. This, seemingly contradicting, practice highlights the gaps in the fundamental understanding of the nature of defects in perovskite materials. In the first funding period of the project
