题 目: Ion Migration in Organic/inorganic Hybrid Perovskite Solar Cells
主讲人: 袁永波（
主持人: 石东（教授）
简 介:
Organometal trihalide perovskite (OTP) solar cells might be the next commercially available thin film solar cells due to its high power conversion efficiency and low fabrication cost, which should attributed to the fantastic optoelectronic properties of OTP materials. Recent studies disclosed that OTP is actually a kind of soft materials with both charge carrier conduction and ionic conduction. Increasing observations indicate that mobile ions impact a lot on the electronic/optoelectric properties of OTP film, which hence have raised substantial related studies already. In this presentation, we will introduce the current understanding of ion migration behaviors in OTP solar cells and discuss its impacts on the photovoltaic device efficiency and stability, and the recent discovered anomalous photovoltaic effect in OTP materials will also be introduced.
