| Abstract: | A soluble thiophene copolymer having polar and non polar side groups was synthesized and its photovoltaics performance was investigated. The synthesized copolymer was characterized using Nuclear Magnetic Resonance (NMR) and optical spectroscopy. Dye sensitized solar cells were fabricated using this copolymer as sensitizer. An open-circuit voltage of 0.50V, a short-circuit current density of 1.195 mA/cm2 and an overall power conversion efficiency of 0.3% were measured. |
