The author of the article were Duvva, Naresh; Prasanthkumar, Seelam; Giribabu, Lingamallu. The article conveys some information:
Structural modifications of porphyrin sensitizers have shown significant impact on incident photon to current generation while applied into dye sensitized solar cells. Nevertheless, various positional alterations of donor/acceptors attached porphyrin dyes reported until now in which A3B based sensitizers received much attention in DSSCs. Herein, we reported A3B type hexyl-phenothiazine appended porphyrins (G10 and G11) utilized as sensitizer with liquid redox electrolyte results the efficiency of 5.4% which is highest performance amongst A3B type sensitizers reported. Optical and electrochem. properties of G10 and G11 suggested that photoinduced intramol. electron transfer mechanism occurred from donor hexyl-phenothiazine to acceptor acetic acid via porphyrin macrocycle. D. functional theory calculations revealed that lowest occupied MO of dyes close to the conduction band of TiO2 facilitates efficient electron injection from dye to nanoparticles. Incident photon to electron conversion efficiency (IPCE) spectra and J-V curve of dyes depict broad band from 350 to 750 nm in the range of >50-55% as a result power conversion efficiency (η) of 5.11-5.40%. Therefore, design of diverse mol. structures pave the way for improved efficiency and durability of photovoltaic devices. After reading the article, we found that the author used 4-Iodobenzoic acid(cas: 619-58-9Computed Properties of C7H5IO2)
4-Iodobenzoic acid(cas: 619-58-9) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Computed Properties of C7H5IO2 Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
