To explore a good candidate for solar cell applications as an alternative to lead-independent materials, we calculated the structural and mechanical stability of Rb2TlSbX6 (X = Cl, Br, I) compounds with PBEsol potential. The optoelectronic thermoelectric behaviors these are computed TB-mBJ Our results indicate that materials possessed excellent structural, mechanical, thermal on basic values their Goldsmith's, elastic parameters negative formation energies. dynamic is observed through phonon dispersion curve found all dynamically stable. Poisson Pugh ratios positive value Cauchy's pressure ductile nature materials. We low direct bandgaps Rb2TlSbCl6, (1.486 eV), Rb2TlSbBr6 (2.07 Rb2TlSbI6 (1.04 eV) unlike majority halide double perovskite family have large bandgap in literature. In addition, optical characteristics show absorption conductivity reflectivity energy loss at small ranges. According findings, halogen-based potential be employed photovoltaic absorb applications. Furthermore, Seebeck coefficient, high-power factor figure merit (ZT) room temperature also ensured significance generators.
