Zero energy buildings a step closer following UNSW solar breakthrough
Buildings with roofs, facades and windows swathed in solar are a step closer following news that the University of NSW has broken efficiency records for CZTS thin-film solar.
While traditional thin-film solar is made from scarce, expensive and toxic materials, CZTS thin-film technology uses the benign and abundant materials copper, zinc, tin and sulphur – meaning price spikes are less likely as demand increases, and safety is less of a concern.
