First principles study of structural, electronic and optical properties of Cs-doped HC(NH2)2PbI3 for photovoltaic applications

Investigation of the Stability of Methylammonium Lead Iodide (MAPbI3) Film Doped with Lead Cesium Triiodide (CsPbI3) Quantum Dots under an Oxygen Plasma Atmosphere

“…The doping of CsPbI 3 QDs usefully inhibits the formation of PbI 2 and even avoids the degradation of MAPbI 3 . This is due to the decrease of hydrogen bonding in MAPbI 3 and the increase of octahedral tilting by the Cs ion exchange process [ 25 , 26 ]. When the power was higher than 60 W, the peaks of MAPbI 3 at 14° and 28° disappeared, and then the (001) orientation of PbI 2 emerged at the peak position of 12°.…”

A review on theoretical studies of structural and optoelectronic properties ofFA‐based perovskite materials with a focus onFAPbI3

“…Hybrid perovskite materials reveal excellent optical properties that make them a promising candidate to be used in not only solar cells but also light detectors 54,61 and light-emitting diodes 206,207 ; For instance, hybrid perovskite materials have direct bandgap semiconductors with large absorption coefficients about 104-105 cm À1 . 208 Thereby, many efforts have been made to investigate and develop the optical properties and photovoltaic performance of perovskite materials such as high absorption coefficient, 77,209 wide spectral range, 210,211 high mobility, 212 small effective masses, 188 and low trap-state density. 213 Accordingly, many efforts have been made to investigate the impact of substitution at A site in FA cation in hybrid perovskites materials.…”
