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.

该项目旨在开发高性能光铁电材料，用于广泛的光效率转换技术，例如光伏和光催化技术。在过去的50年中，铁电光伏技术仅是学术上的好奇心，因为它们相对于流行的半导体光伏电动机的能量转换效率低。该项目的目的是通过引入与电子键盘结合的离子共固体来解锁铁电光伏的潜力，并将其融合到承诺的铁电材料中，并研究所得的光激发电子和电气性能。可以预计，该提议的项目的结果将为最佳的铁电可见光吸收提供解决方案，以实现铁电材料中的高功率转化效率，以实现实用的光持仪应用。
