Efficient organic solar cells with very low driving force


It was believed that efficient operation of organic solar cells requires a large driving force, which limits the efficiency of organic solar cells. Now, a large group of researchers led by Feng Gao, lecturer at IFM at LiU, He Yan at the Hong Kong University of Science and Technology, and Kenan Gundogdu at the North Carolina State University have developed efficient organic solar cells with very low driving force.This implies that the intrinsic limitations of organic solar cells are no greater than those of other photovoltaic technologies, bringing them a step closer to commercialisation.
