Radiative cooling tech based on polydimethylsiloxane film increases PV module generation by up to 3.72%

Scientists in China have proposed to use polydimethylsiloxane films doped with soda glass to reduce solar module temperature. The coating achieved solar transmittance of 94. 8% and sky window emissivity of 95. 3%. A group of researchers from China's Shandong University and Xi'an Jiaotong University has developed a radiative cooling (RC) cover for PV panels that can reportedly reduce their operating temperature by up to 3. 72%. Radiative cooling occurs when the surface of an object absorbs less radiation from the atmosphere and emits more. As a result, the surface loses heat and a cooling effect ...
