Abstract This work provides an investigation into enhancing the performance of solar cells based , using a unique combination density functional theory (DFT) calculations and SCAPS‐1D device modeling. Through DFT, we determine that has indirect bandgap 1.84 eV, closely matching experimental value 1.80 eV. The material's electronic structure is largely influenced by cobalt chlorine atoms, while nitrogen hydrogen contribute to lattice stability. Optical analysis reveals initial absorption peak at 5.11 along with effective in visible spectrum (1.6–3.2 eV). To ensure SCAPS simulations produce realistic results, benchmarked against reference (FTO///Spiro‐OMeTAD/Au) found close agreement data. With confidence SCAPS, utilized DFT‐derived parameters for including bandgap, masses, states, mobilities, permittivity, as inputs further simulation. In optimization phase, such thicknesses hole electron transport layers, defect densities, doping concentrations, temperature effects are systematically adjusted. These optimizations result notable power conversion efficiency (PCE) 19.71% room temperature.

Small, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Semi‐transparent perovskite solar cells (STPSCs) have shown great potential in Building Integrated Photovoltaics (BIPVs). Inverted STPSCs with nickel oxide (NiO x ) hole transport layer are preferred for BIPVs due to their excellent stability and transparency. However, performance is limited poor NiO /perovskite interface leading non‐radiative recombination degradation. Here, the study uses different fluorinated benzoic acids viz. 4‐fluorobenzoic acid, 3,4‐di‐fluorobenzoic 3,4,5‐tri‐fluorobenzoic improve effect of fluorine substitution on acid. Chemical interaction between these molecules can remove hydroxyl groups from surface, mitigating defect states which results reduced recombination. modified acid demonstrate a champion power conversion efficiency (PCE) 15.12% an average visible transmittance (AVT) ≈30%. Modified unencapsulated device maintains 90% its initial PCE after 1500 hours, stored 30–35% humidity, demonstrating superior stability. This emphasizes role buried interfacial passivation development building facades, windows, or skylights.

Previous studies have shown that the degradation rate of metal halide perovskites in an ambient atmosphere increases with amount tensile stress, which primarily arises from coefficient thermal expansion mismatch substrate. In this work, we show first evidence stress relaxation perovskite films resulting moisture uptake. Indeed, for multiple compositions observe tension relaxes rapidly conditions, as compared to inert quartz crystal microbalance measurements showing a mass density increase on similar time scale indicative The uptake at free surfaces, including grain boundaries, can reduce constrained film, how adatom diffusion reduces residual following thin film formation. Unfortunately, catalyze other mechanisms such PbI2 formation or transition nonperovskite structural phase. Stress-induced is especially important problem all-inorganic because they are annealed much higher temperatures, causing high stress. It explains unusually poor stability these perovskites. Using diethyl ether antisolvent bath attach CsPbI2Br substrate lower temperature, reduced initial strain 0.43 ± 0.04% 0.12 0.05%, thus reducing driving force and improving its phase by over factor 15.
