A comprehensive investigation of the SrAsX (X = F/Cl/Br) inorganic cubic perovskites' strain-induced structural, electronic, optical, and mechanical properties with solar cell applications.

In comparison to the lead halide perovskites, nowadays, lead-free halide perovskites have demonstrated a number of benefits, including efficient optical absorption, increased stability, variable bandgap, excellent mobility of carriers, non-toxicity, abundant raw ingredients, and low manufacturing cost. The use of the Perdew-Burke-Ernzerhof (PBE) and Heyd-Scuseria-Ernzerhof (HSE) hybrid functional inside the quantum espresso software allowed for a thorough examination of these materials, potentially leading to improvements in the development of ecologically acceptable and economically sustainable perovskite-based products. This work has extensively examined the effects of compressive and tensile strain on the structural, optical, and electronic characteristics of the inorganic cubic perovskite SrAsX (X = F, Cl, Br) with varying X anion using first-principles density-functional theory (FP-DFT).

Numerical analysis and device modelling of a lead-free SrPI/SrSbI double absorber solar cell for enhanced efficiency.

Halide perovskites are the most promising options for extremely efficient solar absorbers in the field of photovoltaic (PV) technology because of their remarkable optical qualities, increased efficiency, lightweight design, and affordability. This work examines the analysis of a dual-absorber solar device that uses SrSbI as the bottom absorber layer and SrPI as the top absorber layer of an inorganic perovskite through the SCAPS-1D platform. The device architecture includes ZnSe as the electron transport layer (ETL), while the active layer consists of SrPI and SrSbI with precise bandgap values.
