Synthesis, characterization and photovoltaic properties of 2-fluor-derivatives of porphyrin as near-infrared dyes
Author(s): Ashis K Sarker
Abstract: We designed and synthesized PznDPP-P-2F molecule, in which a porphyrin ring was linked to two diketopyrrolopyrrole units by ethynylene bridges. This new donor material is characterized by using NMR, MALDI-TOF-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 830 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 OPV based on PznDPP-P-CF3 showed JSC of 11.32 mA/cm2, VOC of 0.66 V, a FF of 0.62, the overall power conversion efficiency of (η) 4.65%. The easy synthetic route and purification technique provide the viability of this donor material as future OPV development.
