AbstractThe high efficiency all-small-molecule organic solar cells (OSCs) normally require optimized morphology in their bulk heterojunction active layers. Herein, a small-molecule donor is designed and synthesized, and single-crystal structural analyses reveal its explicit molecular planarity and compact intermolecular packing. A promising narrow bandgap small-molecule with absorption edge of more than 930 nm along with our home-designed small molecule is selected as electron acceptors. To the best of our knowledge, the binary all-small-molecule OSCs achieve the highest efficiency of 14.34% by optimizing their hierarchical morphologies, in which the donor or acceptor rich domains with size up to ca. 70 nm, and the donor crystals of tens of nanometers, together with the donor-acceptor blending, are proved coexisting in the hierarchical large domain. All-small-molecule photovoltaic system shows its promising for high performance OSCs, and our study is likely to lead to insights in relations between bulk heterojunction structure and photovoltaic performance.

Donor Acceptor

Introducing a proper amount of the third component in ternary blend organic solar cells can result in a significant decrease of docking PC71BM with the central electron-donating unit of electron donors and thus suppress charge recombination.

Novel Strategy

A novel strategy is proposed to construct simple-structured SMAs using a weakly electron-deficient thiazolothiazole (TTz) core. The highest PCE of 8.77% is recorded for TTz1-based OSCs, which is the highest efficiency to date among non-fullerene OSCs with simple-structured SMAs.
