Passively Ultra Cooling Patch Enabling High‐Efficiency Power‐Water Cogeneration
Advanced Materials, EarlyView.Photovoltaics are the most viable solar energy technology. This work introduces an ultra‐cooling patch (UCP) for passive thermal management of PV, achieving a 28% increase in power density and a water production rate of 2.2 L day−1. The enhancement results from the aligned channels and configurable heat transfer pathways of the UCP, which significantly
