Simple organic donors based on halogenated oligothiophenes for all small molecule solar cells with efficiency over 11%

Recent work has emphasized the pivotal role of halogen substituents in the development of polymer donors or small-molecule (SM) acceptors for efficient bulk-heterojunction (BHJ) solar cells. However, the application of-F or-Cl substitutions in the design of SM donors is yet to receive similar considerations. In this contribution, we report a set of oligothiophene derivatives (2F7T and 2Cl7T) with halogenation at the central thienyl moiety. Such halogenation is shown to induce a sufficient increase in ionization potential (IP; i.e. deeper HOMO) to modify the electron-donating and-transporting characteristics of the molecules. When combined with a low-bandgap SM acceptor (Y6), the devices with 2Cl7T achieved power conversion efficiencies (PCEs) of up to ca. 11.5% (vs. ca. 2.5% for non-halogenated donor DRCN7T based devices), representing the best photovoltaic performance of oligothiophene donors.

Thieno[3,4-c]pyrrole-4,6-dione-3,4-difluorothiophene Polymer Acceptors for Efficient All-Polymer Bulk Heterojunction Solar Cells

Branched-alkyl-substituted poly(thieno[3,4-c]pyrrole-4,6-dione-alt-3,4-difluorothiophene) (PTPD[2F]T) can be used as a polymer acceptor in bulk heterojunction (BHJ) solar cells with a low-band-gap polymer donor (PCE10) commonly used with fullerenes. The “all-polymer” BHJ devices made with PTPD[2F]T achieve efficiencies of up to 4.4 %. While, to date, most efficient polymer acceptors are based on perylenediimide or naphthalenediimide motifs, our study of PTPD[2F]T polymers shows that linear, all-thiophene systems with adequately substituted main chains can also be conducive to efficient BHJ solar cells with polymer donors.
