Geometrical parameters, electronic structures and photophysical properties of three new
triphenylamine (TPA) and diphenylamine (DPA) based electron donor materials M1 M3 (for …

The 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 …

A bis-porphyrin compound (VC7) has been used as a donor along with two acceptors,
namely, PC71BM and IT-4F (non-fullerene), for the production of efficient all-small-molecule …

The effects of replacing the phenyl rings of triphenylamine (TPA) by naphtyl groups are
analysed on a series of push-pull molecules containing a 2-thienyl-dicyanovinyl acceptor …

Low cost, high efficiency, and high stability are the three key issues of organic solar cells
(OSCs) that should be carefully considered to meet the requirement of future commercial …

A novel p-type organic semiconductor (p-OS), P2TBR, based on a non-fused ring structure
of thiophene–benzene–thiophene (TBT) as the core and 2D-conjugated benzodithiophene …

Recently, materials development in solution processable organic solar cells (OSCs) has
focused upon so-called 'low band-gap'(or more precisely narrow optical gap) polymers …

Small‐molecule donors for solar cells are usually end‐capped with π‐systems or aliphatic
chains extending the π‐conjugation of the molecules's backbone. Compared with alkyl …

Two new conjugated acceptor–donor–acceptor (A–π-D–π-A) compounds having a Zn-
porphyrin acting as donor and linked by ethynylenes to one or two units of …

Two isostructural low-band-gap small molecules that contain a one-atom substitution, S for
Se, were designed and synthesized. The molecule 7, 7′-[4, 8-bis (2-ethylhexyloxy) benzo …
