Efficient Sensitization of Nanocrystalline TiO₂ Films by a Near‐IR‐Absorbing Unsymmetrical Zinc Phthalocyanine

Electrochemical and spectral studies of self-assembled monolayer of 1,8,15,22-tetraaminophthalocyanatocobalt(II) on indium tin oxide surface

“…The ordered films formed by self-assembly method [7] proved to be a versatile one in contrast to other methods including electropolymerization [8], Langmuir-Blodgett deposition [9], vapor-phase deposition [10] and casting [11]. Previously, self-assembled monolayer (SAM) of MPc's on titanium dioxide, silicon and gold surfaces was prepared by tethering the Pc macrocycle with carboxylic acid, trichlorosilyl, and thiol or thioether, respectively [12][13][14]. Even though these compounds can successfully form SAM on different substrates, it is associated with several drawbacks such as low yield in synthesis, poor stability in atmospheric conditions and incompatible for optical studies [15].…”

Benzimidazole-functionalized ancillary ligands for heteroleptic Ru(ii) complexes: synthesis, characterization and dye-sensitized solar cell applications

“…Among various components, the sensitizer is one of the vital component to improve the efficiency and durability of the device. During last two decades, various photosensitizers for DSSC such as ruthenium dyes, 5-7 tetrapyrrolic sensitizers (zinc porphyrin and phthalocyanines), [8][9][10][11][12] and metal-free organic dyes [13][14][15] have been developed to serve as efficient harvesters of sun light. Very recently, a new concept has been developed on perovskite based DSSC that has shown an efficiency of up to 20.1%.…”

Organic-Ruthenium(II) Polypyridyl Complex Based Sensitizer for Dye-Sensitized Solar Cell Applications

“…The photosensitizer plays a crucial role in achieving higher photoconversion efficiency and has been actively studied globally. A wide variety of sensitizers have been studied for DSSC that includes various metal complexes, organic molecules, porphyrins, and phthalocyanines and so forth [6][7][8][9]. But only ruthenium-based sensitizers could have marked their way towards commercialization because of their high photoconversion efficiencies.…”
