Processing-composition-structure effects on the optical band gap of KNbO3-based ceramics
This present work is focused on band-gap engineering of solid-solutions based on KNbO3, which was proposed as a promising photoferroelectric (Grinberg et al., 2013). The strategy to narrow the band-gap of the parent KNbO3 (3.22 eV), relies on replacing Nb5+ by lower valence transition metals (Me3+) …

Photovoltaic properties and size-pH phase stability of iron disulfide from density-functional theory
Despite its exceptional optical absorptivity, suitable band gap, and earth abundance, the low open-circuit voltage of pyrite FeS₂ has remained the biggest challenge preventing its use in photovoltaic devices. Two widely-accepted causes are: (i) Fermi level pinning caused by intrinsic surface states …

Electron-reflector strategy for CdTe thin-film solar cells
… record CdTe efficiency (16.5%) is much less than its theoretical maximum efficiency (29%), primarily because the open-circuit voltage (0.845 V) is well below what is expected for its band gap (1.5 eV). The incorporation of an electron reflector is a strategy to improve the open-circuit voltage of …
