Understanding and controlling of photoferroelectricity for photoenergy uses

该项目旨在开发高性能光铁电材料，用于广泛的光能转换技术，如光催化和光催化。在过去的50年里，铁电光致变色材料由于其相对于流行的半导体光致变色材料的低能量转换效率而仅仅是学术上的好奇心。本项目旨在通过在铁电材料中引入离子共取代，并结合电子钉扎，研究其光激发的电子和电学性质，从而释放铁电光致发光的潜力。预计该项目的成果将为最佳铁电可见光吸收提供解决方案，以实现铁电材料在实际光能应用中的高功率转换效率。

The project seeks to develop high performance photoferroelectric materials for a wide range of photoenergy conversion technologies like photovoltaics and photocatalytics. For the past 50 years, ferroelectric photovoltaics have only been an academic curiosity due to their low energy conversion efficiency relative to the popular semiconductor photovoltaics. This project aims to unlock the potential of ferroelectric photovoltaics by introducing an ion co-substitution, which is coupled with electron-pinning, into promising ferroelectric materials and investigating the resultant photo-excited electronic and electrical properties. It is anticipated that the outcomes from this proposed project will provide a solution for optimal ferroelectric visible light absorption to achieve high power conversion efficiency in ferroelectric materials for practical photoenergy applications.
