Stabilization of lead-free bulk CsSnI<sub>3</sub> perovskite thermoelectrics <i>via</i> incorporation of TiS<sub>3</sub> nanoribbon clusters
The intense research for efficient low-temperature thermoelectric materials drives the exploration of innovative compounds and composite systems. This study investigates the effects of integrating low-dimensional titanium trisulfide (TiS<sub>3</sub>) into bulk tin-based halide perovskites (CsSnI<sub>3</sub>) for thermoelectric applications. The incorporation of small amounts of two-dimensional titanium trisulfide (TiS<sub>3</sub>) into CsSnI<sub>3</sub> not only significantly enhanced the structural stability of the composite material and suppressed oxidation processes but also ensured that its initial electrical properties, including conductivity and the Seebeck coefficient, remained stable for at least 24 hours-unlike the pristine CsSnI<sub>3</sub> sample. These findings emphasize the potential of low-dimensional TiS<sub>3</sub> as an effective additive for stabilizing the thermoelectric performance of CsSnI<sub>3</sub>-based materials over time.
