Tuning Thermal Conductivity of Hybrid Perovskites through Halide Alloying.

ABSTRACT: Tuning the thermal transport properties of hybrid halide perovskites is critical for their applications in optoelectronics, thermoelectrics, and photovoltaics. Here, an effective strategy is demonstrated to modulate the thermal transport property of hybrid perovskites by halide alloying. A highly tunable thermal conductivity of mixed-halide hybrid perovskites is achieved due to halide-alloying and structural distortion. The experimental measurements show that the room temperature thermal conductivity of MAPb(Br_xI_{1- x})₃ (x = 0─1) can be largely modulated from 0.27 ± 0.07 W m^-1 K^-1 (x = 0.5) to 0.47 ± 0.09 W m^-1 K^-1 (x = 1). Molecular dynamics simulations further demonstrate that the thermal conductivity
