Summary This work presents different numerical methods that are used for the first time in solving Perovskite solar cells (PSCs). Classical differential quadrature, sinc, and discrete singular convolution (Regularized Shannon and Delta Lagrange kernels) methods are employed for studying this problem. The governing equations are derived based on Poisson's and continuity equations. The different quadrature techniques are introduced to convert the system of nonlinear partial differential equations to nonlinear algebraic system. Then, an iterative method is used to solve this system. Convergence and efficiency of the obtained results with error ≤10−8 depend on various computational characteristics for each technique. The computed results match with previous experiment, exact, finite difference, SCAPS 1‐D simulation software, and finite element scheme. Then, the comprehensive parametric study is explored to show the effects of density states, gap energy, thickness, temperatures, lifetimes, wavelength, absorption coefficient, recombination prefactor, and recombination mechanisms whether direct or indirect on power conversion efficiency (PCE) and charge transport of solar cells with and without interface material. After all that have been studied on PSCs, it was found that the best value of PCEs was 32%. Thus, the computed results of the present schemes may be useful for improving the performance level of PSCs.

The development of efficient all perovskite tandem solar cells has faced challenges related to current matching and optical losses. In this work, a design of a non‐coplanar three‐terminal (3T) all perovskite tandem solar cell is presented, which consists of a p‐i‐n inverted NiOX‐based CsPbI2Br perovskite top cell, and a FA0.6MA0.4Sn0.5Pb0.5I3 perovskite bottom cell with back‐contact (BC) device structure. It effectively mitigated the optical losses introduced in non‐absorbing layers and resulted in a 2.9% absolute efficiency improvement compared to that of planar sandwich‐type 3T tandems. Both optical and electrical characteristics of the multi‐terminal tandem cells are investigated. Then, it is focused on understanding the impact of top cell thickness on overall non‐coplanar BC 3T‐tandem performance, considering low‐energy photon optical reflection and carrier transport distance. Following optimizations of energy level and device structure, an efficiency of 32.16% is achieved, with non‐coplanar BC 3T device architecture: top cell consisting of hole extraction layer (ITO/NiOx), CsPbI2Br absorber layer, and electron extraction layer (ZnO/FA0.6MA0.4Sn0.5Pb0.5I3/SnO2/Ag); and bottom cell (Ni/NiOx/FA0.6MA0.4Sn0.5Pb0.5I3/SnO2/Ag); bottom perovskite layer has two functions, one is electron transport layer for top cell, and the other is low‐energy photon absorption layer in bottom cell. It provides insight and a promising pathway for manufacturing high‐efficient all perovskite tandem solar cells.

Perovskite solar cells, a third‐generation photovoltaic technology, have recently emerged as a game‐changing innovation. However, lead (Pb) is a toxic heavy metal, and it is crucial to explore lead‐free perovskite solar cells with continuously improving efficiency for long‐term development. Recently, materials researchers have discovered a lead‐free double perovskite solar cell material, Cs2InBiBr6 with a small direct bandgap of 1.27 eV and strong thermodynamic and mechanical structural stability. The power conversion efficiency of Cs2InBiBr6‐based perovskite solar cells is not reported yet. To investigate its potential, a solar cell capacitance simulator to analyze the solar cell structure of FTO (Fluorine Doped Tin Oxide)/ETL (Electron Transport Layer)/Cs2InBiBr6/HTL (Hole Transport Layer)/Au, selecting appropriate hole transport materials and electron transmission materials to achieve high efficiency is used. Moreover, this study explores the impact of several factors, including absorber layer thickness, acceptor and donor doping density, and the influence of total defect density of the perovskite and interface layers on the performance of solar cells. Advanced device characterization methods such as Mott‐Schottky analysis are performed to unravel the effect of interfaces on the device performance. The solar cell with the device structure FTO/TiO2/Cs2InBiBr6/Cu2O/Au achieves an outstanding PCE of 23.64% demonstrating the immense potential of Cs2InBiBr6 as a lead‐free double perovskite solar cell absorber layer.
