Barocaloric materials, undergoing thermal changes in response to applied pressure, may provide energy efficient and zero-emission solid-state cooling. Here the authors report a mechanism for achieving large reversible barocaloric effects near ambient temperature, leveraging volume and conformational entropy changes within the organic bilayers of two-dimensional metal–halide perovskites.
