摘要: This report describes the synthesis of a novel porphyrin–triazine compound bearing three porphyrin macrocycles connected to each other via triazine central unit, and investigation its properties for possible use in bulk heterojunction solar cells (BHJ-SCs). The serve as light harvesting antennae, while triazines have been widely known be charge extracting promoters. According cyclic voltammetric studies, Highest Occupied Molecular Orbital (HOMO) Lowest Unoccupied (LUMO) energy levels target were estimated at −5.4 −3.5 eV versus vacuum, respectively. Photoluminescence measurements blended films phenyl-C61-butyric acid methyl ester (PCBM) or poly(3-hexylthiophene) (P3HT) indicated that transfer was when used an electron donor together with PCBM acceptor. Additionally, surface morphology different donor:acceptor ratios investigated by atomic force microscopy (AFM). Upon variation weight ratio thickness organic layer, short circuit current density (JSC) BHJ-SCs fabricated herein improved up approximately 2.25 mA cm−2.
