Synthesis and Photovoltaic Properties of Organic Photosensitizers Based on Phenothiazine Chromophore for Application of Dye-Sensitized Solar Cells.

We developed organic dye containing the multi-chromophororic system in a molecule by connecting two individual chromophores with alkyl chain directly forusein DSSCs. Each of chromophore contains phenothiazine moiety as an electron donor and various electron acceptor/anchor to identify the effects of the number of electron acceptor and the kind of electron acceptor on the performance of DSSCs. The molecular structure having multi-chromophoric system containing cyanoacrylic acid moieties provided about 10% higher Jsc value than their counter parts of single-chromophore type.
