Nanotechnology Center Makes Flexible Solar Cell Breakthrough
Salem, NC - At a time when oil prices are reaching record highs and people are bracing for winter heating bills, researchers at Wake Forest University's Center for Nanotechnology and Molecular Materials have made significant strides in improving the efficiency of organic or flexible solar cells.
Traditional silicon solar panels are heavy and bulky and convert about 20 percent of the light that hits them to useful electrical power. For years, researchers have worked to create flexible, or "conformal," organic solar cells that can be wrapped around surfaces, rolled up or even painted onto structures, but the best scientists have been able to do is about 3 percent efficiency, until now.
