Organic solar

Organic solar cells with 11.6% efficiency have been developed by researchers at Ulsan National Institute of Science and Technology, UNIST, in South Korea. HyeSung Park and Chang Duck Yang and their colleagues have given the organic photovoltaic materials a boost by applying a macromolecular additive, a well-known n-type semiconducting conjugated polymer, P(NDI2OD-T2), poly{[N,N′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis (dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)}.
