Elucidating the Effect of Ferroelectricity in Bismuth Ferrite Solar Cells

ABSTRACT To investigate the photoresponse of metal‐ferroelectric‐metal (MFM) devices, we sandwich polycrystalline bismuth ferrite between two electrodes of similar work function. We use calcium‐substitution on the A‐site to tailor the properties of bismuth ferrite Bi 1‐x Ca x FeO...
