Perovskite absorption coefficient
WebMar 19, 2024 · Rare earth nickel-based perovskite oxides (RENiO3) have been widely studied over recent decades because of their unique properties. In the synthesis of RENiO3 thin films, a lattice mismatch frequently exists between the substrates and the thin films, which may affect the optical properties of RENiO3. In this paper, the first-principles calculations … WebJan 4, 2024 · The first results show that the perovskite KGeI 3 compound has a high absorption coefficient which is good for photovoltaic applications but the inconvenience is its lowest bandgap 0.502 eV. We tried the strain effect under different percentages looking for an amelioration of the bandgap value.
