POROUS FERROELECTRIC MATERIALS FOR ENERGY TECHNOLOGIES
Solar container materials and ferroelectric materials
We review developments in this eld, with a particular emphasis on the materials known to display the APE/BPE (e.g. ZnS, CdTe, SbSI), and the theoretical explanation. Critical analysis is complemented with rst-principles calculation of the underlying electronic structure.. The application of ferroelectric materials (i.e. solids that exhibit spontaneous electric polarisation) in solar cells has a long and controversial history. This includes the first observations of the anomalous photovoltaic effect (APE) and the bulk photovoltaic effect (BPE). The recent successful. . Ferroelectric photovoltaic materials and devices utilise the inherent spontaneous polarisation of ferroelectrics to enhance charge separation under illumination. This unique capability enables the generation of photovoltages that can exceed classical semiconductor bandgap limits. By leveraging a. . Both, a large ferroelectric polarization and a lower optical band gap are necessary for a ferroelectric semiconductor to be suitable for solar cells. It has been demonstrated theoretically that a?| Ferroelectricity. Definitions. Ferroelectric Materials. A ferroelectric material is material that. .
