Photovoltaic panels generate electricity, solar thermal collectors provide heat, while cooling is usually supplied by air conditioning systems that themselves consume electricity. As a result, buildings require different technologies competing for the limited space available on roofs and facades.
A solution developed by a team led by Dr. Gan Huang at KIT’s Institute of Microstructure Technology, by contrast, simultaneously provides cooling, electricity and heating from a single surface. This hybrid PDRC-solar system combines photovoltaic and solar thermal technologies with passive daytime radiative cooling (PDRC)...
