“…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:

D_{n} \frac{\partial^{2} n ((), x)}{\partial x^{2}} - μ_{n} ((), \frac{\partial n ((), x)}{\partial x} \frac{\partial φ ((), x)}{\partial x} + n ((), x) \frac{\partial^{2} φ ((), x)}{\partial x^{2}}) + G ((), x) - R ((), x) = 0,

D_{p} \frac{\partial^{2} p ((), x)}{\partial x^{2}} - μ_{p} ((), \frac{\partial p ((), x)}{\partial x} \frac{\partial φ ((), x)}{\partial x} + p ((), x) \frac{\partial^{2} φ ((), x)}{\partial x^{2}}) + G ((), x) - R ((), x) = 0,

\frac{\partial^{2} φ ((), x)}{\partial x^{2}} = \frac{q ((), n ((), x) - p ((), x))}{{italicεε}_{0}},

where n and p are concentrations of electron and hole respectively; D n and D p are coefficients of diffusivities of electron and hole respectively; μ n and μ p are electron and hole mobilities respectively; x is distance; φ is electrostatic potential inside absorber sheet; q is the basic charge; ε is relative permittivity; ε 0 is vacuum permittivity; G is the charge production rate; R is the charge depletion rate.…”

Summary Researchers have at different times focused on designing perovskite solar cells (PSCs) that are flexible yet highly efficient, to enable the fabrication of portable photovoltaic solar cell (PVSC) devices in large quantities. This upcoming organometal trihalide perovskite has high tendencies of being a highly efficient, yet inexpensive solar cell. This is because the solution processing method is carried out at a reduced temperature and increased solar to electricity conversion efficiency (>25%) obtained within few innovative years. The nanostructured morphology and film quality is essential in obtaining functional power conversion efficiency. It could be a great task for the two characteristics to be present, especially within solutions where very good films are in contact with smooth morphological surfaces. A fast increase in the energy conversion efficiency of these PSCs incorporated with metal halides has been recorded. The next line of research should be to extend the existing models to 3D explicit models of the meso‐structured layer, to verify the 1D effective medium method discussed in the literature. Several models have been discussed to that effect. This review intensively discusses several perovskite models in a bid to understand PSCs. The challenges and future perspectives have also been highlighted.

“…The charge carrier photogeneration rate were determined in the spectral range of perovskite absorption on the base of Bouguer-Lambert law [5]: where η is the photons generation of electron-hole pairs coefficient; α is the perovskite absorption coefficient; t is the reflectance from the front surface; is the photon flux density in the spectral absorption range of perovskite. Solar spectrum AM1.5 approximation was made by thermal radiation at temperature 5780 K (Planck's law) [5,7]: ,…”

“…The thickness of perovskite absorber material is one of the most important parameters affecting the solar cell performance. In addition, the charge carrier diffusion length (perovskite quality) in the n-i-p solar cell structure must be large enough to photogenerated charge carriers effectively collection [4,5]. In this paper, the numerical model based on drift-diffusion system semiconductor equations was proposed.…”
