The hydrogel cooling technology was developed by a PolyU team led by Prof. Yan Jerry, Chair Professor of Energy and Buildings, together with Dr. Liu Junwei, Research Assistant Professor of the Department of Building Environment and Energy Engineering. The team's research showed that after applying the hydrogel coating to solar panels, hot-spot temperatures could be lowered by up to 16°C, with the power output increased by as much as 13%.
