Abstract

Recently,the anomalous photovoltaic effect of ferroelectric materials has attracted considerable atten-tion in the construction of efficient solar cells owing to the above-bandgap photovoltage of these ma-terials.In this study,we investigate the anomalous photovoltaic effect of relaxor-based ferroelectric Pb(ln1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3(PIMN-PT)ceramics with large remnant polarization and a nar-row optical bandgap.Excellent photovoltaic performance with an ultrahigh open-circuit voltage of 23 V(575 V/cm)is achieved,which is higher than the open-circuit voltages of all reported polycrystalline ma-terials with similar thickness.The phase structure,microstructure morphology,domain structure,ferro-electric and optical characteristics are analyzed,which could provide clues to the origin of the ultrahigh open-circuit voltage of PIMN-PT ceramics.The results suggest that the relaxor-based ferroelectric PIMN-PT system is a potential candidate for photovoltaic solar energy conversion devices.
