Abstract

Two solution-processible linear organic conjugated molecules with an electron-deficient core and triphenylamine (TPA) end groups, TPA-DCM-TPA and TPA-th-TPA, were used as donor and acceptor materials respectively in fabricating all organic solar cells (OSCs) by spin-coating method. Both the LUMO and HOMO energy levels of TPA-th-TPA are lower than those of TPA-DCM-TPA, which makes TPA-th-TPA a suitable acceptor for the OSCs with TPA-DCM-TPA as donor. The all OSC based on the blend of TPA-DCM-TPA and TPA-th-TPA (1:1, w/w) with LiF/Al as cathode, showed the photo-sensitivity in a broad wavelength range from 380 nm to 700 nm, high open-circuit-voltage (V_oc) of 1.21 V, and a power conversion efficiency of 0.21% under the illumination of AM 1.5, 100 mW/cm². The high V_oc of the device is benefited from the higher LUMO energy level of the TPA-th-TPA acceptor in comparison with that of the traditional acceptor PCBM.
