Abstract

The intense research for efficient low-temperature thermoelectric materials motivates the exploration of innovative compounds and composite systems. This study examines the effects of integrating low-dimensional titanium trisulfide (TiS₃) into bulk tin-based halide perovskites (CsSnI₃) for use in thermoelectric applications. The incorporation of small amounts of two-dimensional titanium trisulfide (TiS₃) into CsSnI₃ not only significantly enhanced the structural stability of the composite material and suppressed oxidation processes but also ensured that its initial electri-cal properties, including conductivity and the Seebeck coefficient, remained stable for at least 24 hours – unlike the pristine CsSnI₃ sample. These findings emphasize the potential of low-dimensional TiS₃ as an effective additive for stabilizing the thermoelectric performance of CsSnI₃-based materials over time.
