Semi-transparent, colored energy glass for greenhouses in hot and desert areas, e.g. for glass facades of buildings, soundproof walls and roofs of electric vehicles. This PV technology, Energy Glass, is semi-transparent, insulating, has the lowest CO2 footprint, the shortest energy payback time, and contains no rare earth elements. Energy glass can be easily recycled with existing processes and channels, among other things to ensure the security of the energy supply of healthcare institutions.
