(543c) Ultralow Thermal Conductivity of Two-Dimensional Metal Halide Perovskites
Author
Proper thermal management of solar cells based on metal halide perovskites (MHPs) is key to increasing their efficiency as well as their durability. Although two-dimensional (2D) MHPs possess enhanced thermal stability as compared to their three-dimensional (3D) counterparts, the lack of comprehensive knowledge of the heat transfer mechanisms dictating their ultralow thermal conductivities is a bottleneck for further improvements in their thermal performance. Here, I will review our efforts into comprehensively understanding and manipulating the intrinsic vibrational properties of 2D MHPs throught advanced atomistic modeling and state-of-the-art experiments. Ultimately, the efficient tuning of their thermal properties can overcome the major challenge of their proper thermal management that limits their stability and prolonged use in devices.
