Perovskite solar cell (PSC) technology is extensively used in commercial sectors, but concerns about the use of lead and degradable components in cells are increasing. A PSC, which is based on lead-free KSnI3, is illustrated through the SCAPS-1D simulation. In this work, different hole transport layers (HTLs; spiro-OMeTAD, Cu2O, NiO, and CuI) and electron transport layers (ETLs; TiO2, CdS, WS2, and ZnO) were simulated with the proposed device configuration and highest power conversion efficiency (PCE). By optimizing thickness variation, doping density, defect density, and back contact, we obtained the highest PCE = 20.99%, FF = 85.24%, J sc = 17.063924 mA/cm2, and V oc = 1.4434 V. These values were higher than those in a previous study on a KSnI3-based PSC with phthalocyanine-based CTLs having PCE = 11.91% and on a TiO2, spiro-OMeTAD-based PSC with PCE = 9.776%. To achieve the final optimization result of PCE = 20.99%, we used CuI as the HTL, ZnO as the ETL, and KSnI3 as the absorber layer. The FTO/ZnO/KSnI3/CuI/Au device structure provides an efficient and reliable solution for realizing remarkable efficiency in PSCs.

“…The current state-of-the-art technique followed by the entire scientific community to maximize power conversion efficiency (PCE) of simulated SCs is sequential optimization of three controllable SC parameters namely, layer thickness (t), carrier concentration (N A/D ) and defect density (N t ) using various device simulation software like SCAPS and SETFOS [8][9][10][11][12][13][14][15][16][17][18]. This approach of sequential SC parameter optimization can be referred to as t-N A/D -N t optimization sequence.…”

This paper questions the validity of t-NA/D-Nt technique for solar cell optimization and establishes the scientifically and experimentally-justified NA/D-Nt-t parameter optimization sequence for the same. Fundamental mathematical formulations considering numerous physical perspectives are presented for scientific justification of newly proposed optimization procedure. This is followed by an in-depth comprehensive analysis on sequence of parameter optimization applied in numerous widely-implemented solar cell fabrication techniques. It is found that, in each fabrication technique, the same optimization sequence of NA/D-Nt-t is implemented. Along with this, simulation study of sample solar cell is presented for further analysis of our conceptualization. It is identified that the time at which initial values of NA/D and Nt are replaced by the optimized ones to convert the initial solar cell to an optimized one, the value of absorber thickness at which solar cell produces maximum yield also changes. It was observed that NA/D-Nt-t optimization sequence increased device efficiency from 6.97% to 17.05% (144.6% increment) as compared to 55.8% increment from 6.97% to 10.86% in case of conventional t-NA/D-Nt optimization sequence. Moreover, only the NA/D-Nt-t approach produced EQE graph that matches with the experimentally-observed EQE curves of device. Hence, the newly proposed scientifically and experimentally-justified NA/D-Nt-t optimization sequence proposed for first time in this paper, truly optimizes solar cell device so that it offers maximum-possible efficiency reliably.

“…In recent eras, the rapidly advancing PV technology i.e., perovskite solar cell (PSC) emerges as the most auspicious contender [19][20][21]. Currently, organic-inorganic hybridperovskite materials have garnered significant interest due to their tremendous optical and electrical properties including higher absorption coefficient, tunable bandgaps, high carrier mobilities, long charge-carrier diffusion lengths, low-exciton binding energies [19,[22][23][24][25][26][27][28][29].

All inorganic cesium lead-based perovskite solar cells (PSCs) have gained attention as alternative absorbing materials owing to their exceptional thermal stability. However, these devices are suffer from transmission and thermalization losses. Therefore, a novel grading approach is used in CsPbI3-x Brx perovskite solar cell to reduce the transmission and thermalization losses by enhancing the cell's ability to capture a broad spectrum of light wavelengths and suitably accommodate the material's energy bandgap. In this work, the performance of CsPbI3-xBrx perovskite solar cell with graded bandgap (Eg) and affinity has been explored and analyzed using the simulation SCAPS-1D tool. Different compositions (x) are varied to adjust the bandgap of CsPbI3-xBrx with different grading profiles such as linear, parabolic and beta grading. The graded structure enhances the absorption wavelength range and carrier lifetime. However, it also leads to the redistribution of the electrical field within the device, promoting more effective charge separation and collection. By utilizing this approach, the impact of absorber thickness variations from (50 nm to 700 nm) is also studied and analyzed with respect to grading profiles. Initially, 16.75% power conversion efficiency (PCE) is obtained by calibrating the experimental CsPbI3-xBrx graded solar cell. Then, performance is further improved by adjusting the bandgap with grading profiles, optimizing ETLs/HTLs and achieving optimum PV parameters: short-circuit current density (JSC) of 20.50 mA/cm2, open-circuit voltage (VOC) of 1.35 V, fill factor (FF) of 84.15 % and PCE of 23.11%. The findings of the reported study would significantly provide a path for the development of graded PSC.
