Graphene Organic Photovoltaics: Flexible Material Only a Few Atoms Thick May Offer Cheap Solar Power

While graphene's existence has been known for decades, it has only been studied extensively since 2004 because of the difficulty of manufacturing it in high quality and in quantity.
A University of Southern California team has produced flexible transparent carbon atom films that the researchers say have great potential for a new breed of solar cells.
Organic photovoltaic (OPV) cells have been proposed as a means to achieve low cost energy due to their ease of manufacture, light weight, and compatibility with flexible substrates," wrote Chongwu Zhou, a professor of electrical engineering in the USC Viterbi School of Engineering, in a paper recently published in the journal ACS Nano.
