New passive solar module cooling tech based on lightweight hydrogel

Researchers at Thailand's Vidyasirimedhi Institute of Science and Technology demonstrated a novel hydrogel that has high cooling effect on silicon PV panels. The lightweight technology purportedly enables a temperature drop of 23 C, from 70 to 47 C, and a relative 12. 3% power conversion efficiency increase. Researchers at Vidyasirimedhi Institute of Science and Technology (VISTEC) in Thailand have demonstrated a passive cooling material to address heat-related silicon PV output losses. "We produced a passive cooling system requiring significantly less material but producing very high cooling ...
