New dithienosilole and dithienogermole based BODIPY for solar cell applications

Abstract

We report two efficient donor materials for organic solar cells namely Si-BDP and Ge-BDP, composed by the novel union of thienyl Bodipy wings and dithienosilole/ dithienogermole core. These new donor molecules acquire excellent solubility in organic solvents, extended π-conjugation and low-lying energy levels that are matching with fullerene acceptors, supporting their application as donors in OSCs. Under optimized conditions using PC70BM as an acceptor, attractive PCEs of 4.58% and 4.12% were observed for Si-BDP and Ge-BDP respectively.
