Organic and polymeric photovoltaic (PV) cells show promise as low-cost, light weight, flexible, and renewable energy sources and have been extensively investigated during the past decade. Many desirable properties are dependent on the material's band gap (Eg), therefore determines both the lowest energy absorbance of the material and the energy of any potential emission. Lower Eg values also result in enhanced thermal population of the conduction band, thus increasing the number of intrinsic charge carriers, and the lower oxidation potential associated with a low Eg can result in the stabilization of the corresponding doped (i.e., oxidized) state. We synthesized polythiazole derivative and the structure and photovoltaic properties of polymer was characterized using H-NMR, C-NMR, GPC, TGA, DSC, UV-visible spectroscopy. |
