At present, lead halide PVSKSCs are promising photovoltaic cells but have some limitations, including their low stability in ambient conditions and the toxicity of lead. Thus, it will be great significance to explore lead-free perovskite materials as an alternative absorber layer. In recent years, numerical simulation solar (PVSKSCs) via cell capacitance (SCAPS) method has attracted attention scientific community. this work, we adopted SCAPS for theoretical study (Pb)-free PVSKSCs. A cesium bismuth iodide (CsBi3I10; CBI) perovskite-like material was used The thickness CBI layer optimized. addition, different electron transport layers (ETLs), such titanium dioxide (TiO2), tin oxide (SnO2), zinc (ZnO), selenide (ZnSe), hole layers, spiro-OMeTAD (2,2,7,7-tetrakis(N,N-di(4-methoxyphenylamine)-9,9′-spirobifluorene), poly(3-hexylthiophene-2,5-diyl) (P3HT), poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA), copper (Cu2O), were explored CBI-based device structure FTO/ETL/CBI/HTL/Au studies. studies showed improved performance using TiO2 HTL ETL, respectively. An acceptable PCE 11.98% with a photocurrent density (Jsc) 17.360258 mA/cm2, fill factor (FF) 67.10%, open-circuit voltage (Voc) 1.0282 V achieved under optimized conditions. It is expected that present beneficial researchers working towards development

The scientific community is moving toward a green environment using several nontoxic photon‐absorbing materials like tin, germanium, antimony, and bismuth. Bismuth halides have essential advantages low toxicity, Earth abundance, good chemical stability, optoelectronic behavior which make them suitable for lead‐free perovskite solar cells. Herein, streamlined one‐step spin‐coating technique employed DMF to enhance the morphology of thin films based on BiCl 3 perovskite. resulting methylammonium bismuth halide ((CH NH ) Bi 2 I x Cl 9− display remarkably uniform, pinhole‐free, finely nanostructured morphology, ensuring consistent surface coverage. For development hole conductor‐free Bi‐perovskite cells (PSCs), carbon utilized as both counter electrode extraction layer. device configuration entails FTO/Compact TiO /meso‐TiO /((CH )/Carbon/FTO, novel arrangement Bi‐PSCs. Notably, fabricated devices demonstrate commendable photovoltaic properties, including V oc 280 mV, J sc 0.25 mA, fill factor 0.60, notably elevated power conversion efficiency (PCE) 0.042% has proven significantly advantageous in achieving higher PCE. Furthermore, exhibit robust stability over 40 d when exposed an ambient atmosphere without encapsulation. retain 25% their initial PCE after 168 h, further highlighting durability suitability practical applications.
