Diketopyrrolopyrrole-based acceptors with multi-arms for organic solar cells

Three small molecules SBF-1DPPDCV, SBF-2DPPDCV and SBF-4DPPDCV consisting of a spirobifluorene (SBF) unit as the core and one, two, and four diketopyrrolopyrrole dicyanovinyl (DPPDCV) units as the arms have been designed and synthesized for solution-processed bulk-heterojunction (BHJ) solar cells. The UV-Vis absorption and cyclic voltammetry measurement of these compounds showed that all these compounds have an intense absorption band over 300-750 nm with a LUMO energy level at around -3.87 eV. When pairing with PTB7-Th as the donor, devices fabricated based on PTB7-Th?:?SBF-4DPPDCV blends showed a decent PCE of 3.85%, which is the highest power conversion efficiency (PCE) amongst the three DPP acceptor fabricated devices without extra treatment. Devices with SBF-1DPPDCV and SBF-2DPPDCV acceptors showed lower PCEs of 0.26% for SBF-1DPPDCV and 0.98% for SBF-2DPPDCV respectively. The three dimensional (3D) structure of SBF-4DPPDCV facilitates the formation of a 3D charge-transport network and thus enables a rational electron-transport ability (1.04 × 10-4 cm2 V-1 s-1), which further leads to a higher Jsc (10.71 mA cm-2). These findings suggest that multi-arm acceptors present better performance than one-arm or two-arm molecules for organic solar cells.

Novel electron transmission material and application of same on electronic devices

The invention provides a novel electron transmission material, of which the molecular structure can be described as follows. The electron transmission material, with a group having multiple substituent loci as a nucleus and conjugated groups having different electron withdrawing capabilities as arms, can regulate molecular energy levels by adjusting the difference from the nucleus to the arms, thus enhancing electron delocalization, increasing absorption on visible light, increasing electron mobility, and obtaining an appearance which is beneficial to exciton dissociation and transmission whenthe material is matched with a donor. The material can be applied to electronic devices as an electron transmission material.
