Metal halide perovskites (MHPs) are a versatile class of materials for photovoltaics, light-emitting diodes, photodetectors and spintronic devices. Their composition, structure and dimensionality can be fine-tuned to produce materials with desirable electronic and optical properties for high-performance devices. However, the intrinsically poor thermal conductivity of MHPs makes thermal management a persistent challenge. The resulting heat accumulation…
