We investigated the stability of Sr₃SbCl₃, assessing its structural, thermodynamic, dynamical, and mechanical properties. Using FP-DFT simulations in CASTEP, we comprehensively analyzed the impact of pressure on its physical characteristics. The direct band gap of unstrained Sr₃SbCl₃ at the Γ point is 1.908 eV. Under pressure, it decreases to 1.518 eV at 5 GPa, 1.174 eV at 10 GPa, and further redshifts to 0.863 eV at 15 GPa. The optical properties, such as dielectric functions, absorption coefficient, refractive index, loss functions, reflectivity, and, conductivity, demonstrate a significant ability to absorb light within the visible spectrum, aligning with the material's band characteristics. To investigate solar power capabilities, we examined Sr₃SbCl₃ absorbers in conjunction with CdS ETL of varying thicknesses, defect densities, acceptor densities, interface defect densities, and temperature effect using the SCAPS-1D simulator.

Herein, we have theoretically presented various Cu₂SrSnS₄ solar cell configurations based on inorganic chalcogenide and oxide hole transport layers (HTLs) such as Sb₂S₃, MoS₂, Cu₃BiS₃, NiO, CuAlO₂, and Cu₂O with ZnMgO as electron transport layer (ETL) via SCAPS-1D.

The performance of these solar cells is scrutinized in terms of optoelectronic parameters of the absorber, ETL, HTL, and interfaces where the solar cells without HTL displayed lower performance than those with HTLs. Among the diverse HTL based solar cells, oxide HTL solar cells portrayed superior performance than the chalcogenide HTLs with the best efficiency of 18.48% for Cu₂O solar cells. Further, a comparative analysis is performed using energy band diagrams, electric field, generation, recombination rates, Nyquist plots, and electron distribution in each solar cell. The outcomes reveal that the perfect band alignment with hole and electron barrier of -0.04eV and 0.46eV at the interface of absorber/HTL, large negative electric field, high recombination resistance of 9.4×10⁵ Ω.cm² and low V_OC deficit have led to the dominating efficiency of Cu₂O solar cells among others.
