TLDR
In this paper, photovoltaic effect in ferroelectric thin films with thickness below 100nm was investigated through both theoretical and experimental approaches Unprecedented high power conversion efficiency around ∼028% was achieved with epitaxial (Pb097La003) and Zr052Ti048)O3 O3 thin films, which is about 2 orders of magnitude higher than the reported in literature for ferroelectrics.Abstract:

Bulk Photovoltaic Effect at Visible Wavelength in Epitaxial Ferroelectric BiFeO3 Thin Films
Wei Ji,Kui Yao,Yung C. Liang +2 more
TL;DR: The photovoltaic effect in epitaxial BFO thin films is studied and an open-circuit voltage Voc of 0.3 V is obtained, demonstrating that photocurrent direction can be switched by the polarization direction of the BFO film and that the ferroelectric polarization is the main driving force of the observed photov Holtaic effect.
