Startup New Energy Technologies says that it has made a significant advancement toward large-scale production of “spray on” solar power generating windows.
New Energy debuted a prototype of its “SolarWindow” technology in 2010. It has been gradually moving toward commercialization ever since, and today announced improvements that it says will bring it closer to manufacturing large window panes. That makes future skyscrapers with exteriors that create renewable energy possible – a big advancement for places such as New York City where solar panels may be impractical.
SolarWindow is a process for applying plastic solar films to glass at room temperature and at low pressure. Windows retrofitted with the film can generate energy from the sun’s visible light as well as artificial illumination such as office lighting. They remain see-through, so that the glass’s aesthetic qualities aren’t lost.
