Numerical modeling of perovskite solar cells with a planar structure

Room‐Temperature Red–Green–Blue Whispering‐Gallery Mode Lasing and White‐Light Emission from Cesium Lead Halide Perovskite (CsPbX3, X = Cl, Br, I) Microstructures

“…However, the lifetimes of CsPbBr 3 and CsPbI 3 are much longer, and they are about 36.9 ns (Figure F) and 59.7 ns (Figure I), respectively. The lifetimes of these structures are found to vary at different positions on the substrate (see Figure S4 in the Supporting Information), which is probably due to the variation in thickness and size of these perovskite structures on the substrate . In this case, further investigations on single crystals are needed in the future for an in‐depth understanding of effects of structural properties on the carrier dynamics of these microstructures.…”

An overview of the mathematical modelling of perovskite solar cells towards achieving highly efficient perovskite devices

“…where τ n and τ p are a lifetime of charges; n i is the concentration of the inherent bearer; -For the straight interband non-radiative depletion equation 21,117,120 :…”

“…Moreover, there is growing proof to propose that the movement of ions could be responsible for the prolonged stability of PVSCs. 23 Malyukov et al 117 developed a solar cell model in the drift-diffusion approximations partial-conductor with static equations for calculating concentrations of electrons and holes, and the perovskite potential estimation in terms of Poisson expression is given by References 33, 118:…”

“…The function of surface defects are evaluated based on these approaches by directly considering solvent influences and processing conditions like concentration of different components and processing temperature. 76 Malyukov et al 117 developed models that gave the understanding of PSCs operation mechanism and contribute to their efficiency enhancement. They also discovered that the thickness of the perovskite absorber should be such that enormous photons could be absorbed; although it produces more recombination centre and mitigates the transport of photo-generated charge carrier because of the decrease in electric field.…”
