## Abstract

The use of photoferroic materials that combine ferroelectric and light harvesting properties in a photovoltaic device is a promising route to significantly improve the efficiency of solar cells. These materials do not require the formation of a p-n junction and can produce photovoltages well above the value of the band gap, because of the spontaneous intrinsic polarization and the formation of domain walls. In this perspective, we discuss the recent experimental progresses and challenges for the synthesis of these materials and the theoretical discovery of novel photoferroic materials using a high-throughput approach.
