Abstract
A total green, eco-friendly process for the synthesis of new acceptor molecule [6,6]-phenyl-C-butyric acid pentyl ester (PC61BP) in high yields is carried under aerobic conditions showing better performance as acceptor in organic solar cells. More importantly this process causes the low cost synthesis of PC61BP in good yield without involving harmful and costly catalysts or chemicals.
