Ferroelectric materials for photovoltaics

Abstract

Ferroelectric photovoltaic has been intensively studied during the last years due to possible high efficient charge separation by presence of an internal electric field. Ferroelectric materials show permanent electrical polarization. Ideally, electric contacts would screen the polarization, but if screening is not perfect, it results in the generation of depolarization field. In this report, we study the photoelectric response of LuMnO3 that shows a small bandgap compared to archetypical ferroelectric materials and a sizeable internal polarization. We have studied its photoresponse dependence on polarization state.
