Abstract:

Bulk-heterojunction organic solar cell (BHJ-OSC) utilizes a nanostructured electron donor and electron acceptor blended film to capture and convert solar photons into electrons. Recently, much attention has been focused on non-fullerene organic acceptors, which are used as acceptor materials to replace the traditional fullerene acceptor materials. The exciton-type photon-to-electron conversion efficiencies such as exciton generation and charge separation and transport are largely dependent on the material absorption, frontier molecular orbitals and film-morphology. In this report, I will show our results on the molecular strategies towards efficient small-molecule photovoltaic materials. The results include: (1) The photovoltaic properties from the twisted perylene-dimide dimer acceptors, (2) the photovotaic properties from BODIPy based small molecule donor and acceptor, and (3) the photovoltaic properties from Diketopyrrolopyrrole (DPP) and quinoidal methyl-dioxocyano-pyridine based small molecule donors, in particular, the effects of the end units capping on the DPP main chain and the influence from the anchoring groups terminated on the flexible alkyl chains.
