Cover Feature: Dual‐Function Hydrogel Synthesis for Passive Photovoltaic Cooling for Climate‐Resilient Solar Infrastructure (Sol. RRL 6/2026)

Photovoltaic Cooling In article number e202500913, Chirodeep Bakli and co-workers develop a passive photovoltaic cooling strategy based on perforated hydrogels that leverages daytime evaporative heat dissipation and nighttime atmospheric moisture regeneration. A reduction up to 14.5 °C in module temperatures leading to ~25 % increase in power output is observed with commercial solar modules. This self-regenerating, energy-neutral approach offers a scalable and retrofittable solution for improving photovoltaic performance in high-insolation environments.
