Commercial 'Green' Solar Cells May Be Possible: Pittsburgh PA (SPX) Nov 24, 2011 Developing solar e... (SolarDaily)

Developing solar energy that is low-cost, lightweight, and energy efficient has proven to be one of the greatest challenges the science world faces today. Although current plastic solar cells are low in cost and easy to produce, they are not energy efficient and, therefore, not easily commercialized. With grant funding from the National Science Foundation, researchers at the University of Pittsburgh are predicting a way to produce solar cells that will offer more flexibility in generating green energy. Guangyoung Li, assistant professor of electrical and computer engineering at Pitt, explains that most plastic solar cells today are made from a blend of semiconducting polymers and other carbon-rich molecules. Although this material is usable and costs little, it does not assist with energy efficiency-though it could. Li's solution is to use a method called Kelvin Probe Forc...
