Cheaper, Spray-On Solar Panels Could Appear in Three Years | Business | GreenBiz.com: “AUSTIN, TX — Researchers at the University of Texas have developed a method to create photovoltaic panels at one-tenth the cost of existing technologies using nanoparticle ‘inks’ to generate electricity from the sun.
The group, lead by Brian Korgel in the University’s chemical engineering department, predicts that the technology, which would allow solar panels to be painted on rooftops or the sides of buildings, could be market-ready in three to five years.”
