Abstract

We designed and synthesized Pzn-DPP-P-CF3 molecule, in which a porphyrin ring was linked to two diketopyrrolopyrrole units by ethynylene bridges. This new donor material is characterized by using NMR, MALDITOF-Mass, UV/Visible spectrophotometer and cyclic voltammetry. The resulted material exhibited a very low energy band gap of 1.49 eV and a broad light absorption to 830nm. 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 OPV based on Pzn-DPP-P-CF3showed JSC of 11.02 mA/cm2, VOC of 0.77 V, a FF of 0.54, the overall power conversion efficiency of (η)4.56%. The easy synthetic route and purification technique provide the viability of this donor material as future OPV development.
