We designed and synthesized porphyrin derivatives, in which a porphyrin ring was linked to two diketopyrrolopyrrole-4-fluorobenzene units named Pzn-DPP-P-F by ethynylene bridges. This new donor material is characterized by using 1H NMR, MALDI-TOF-Mass, UV-Visible spectrophotometer and cyclic voltammetry. The resulted material exhibited a very low optical band gap of 1.50 eV and a broad light absorption to 825 nm. The photovoltaic performances of these donor materials were successfully evaluated in organic solar cells. PCBM was used as acceptor moiety in this work. Consequently, the organic photovoltaic device (OPV) based on Pzn-DPP-P-F showed JSC of 12.67 mA/cm2, VOC of 0.69 V, a FF of 0.52, the overall power conversion efficiency of (η) 4.55%. The facile synthetic route and purification technique provide the durability of this donor material as future OPV development.
