03 Jul 2013: Flexible Glass Solar Cells
Could Boost Effectiveness of Solar Shingles

U.S. researchers have developed a solar shingle made of flexible glass that could emerge as an

alternative to conventional roof shingles and drive down the costs of rooftop solar energy systems. Unlike conventional solar panels, which are bulky and breakable, the new solar cell built by the National Renewable Energy Laboratory is durable enough to last for decades, according to MIT’s Technology Review. While typical panels must be mounted on top of asphalt shingles, the glass solar shingles can be nailed directly onto a roof instead of conventional shingles. The cells are made of a pliable material called Willow Glass, which was developed by Corning, the company that also makes the so-called Gorilla glass for iPhone screens. According to researchers, the glass can also utilize cadmium telluride — which can compete on a cost basis with more widely used silicon solar cells — as the solar cell material.
