The Relationship

Three subtle structural changed end-capped acceptors with increased electron withdrawing ability were synthesized and introduced into a planar conjugated backbone. The relationship between molecules bearing the three end-capped acceptors and their photovoltaic properties was studied.

By comparing two-acceptor type (A1–A2–D–A2–A1) with single-acceptor type organic photovoltaic small molecules, a deep understanding of two-acceptors was obtained, which could help potential strategies of molecular design.

Molar Extinction Coefficients

Two novel triads based on a diketopyrrolopyrrole (DPP) central core and two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) units attached by thiophene rings have been synthesised having high molar extinction coefficients. These triads were characterised and used as donor materials in small molecule, solution processable organic solar cells. Both triads were blended with PC71BM as an acceptor in different ratios by wt % and their photovoltaic properties were studied. For both the triads a modest photovoltaic performance was observed, having an efficiency of 0.65%. Moreover, in order to understand the ground and excited state properties and vertical absorption profile of DPP and BODIPY units within the triads, theoretical DFT and TDDFT calculations were performed.
