Abstract
Photovoltaic devices were assembled using a conducting polymer; poly (3-thiophenemalonic acid) sensitized TiO2 electrodes and an electrolyte containing I3â/Iâ redox couple. This cell exhibited a short-circuit photocurrent (Jsc) of â¼6.65Â mAÂ cmâ2, an open circuit voltage (Voc) of â¼355Â mV and an efficiency of 1.5% under the illumination of 100Â mWÂ cmâ2 (AM 1.5). Addition of an ionic liquid, 1-methyl 3-n-hexylimidazolium iodide, into the electrolyte led to an improvement in the cell performances, achieving an overall efficiency of 1.8% under the same illumination. The average cell characteristics of the later devices are Jsc=â¼7.6mAcm-2, Voc=365mV with a fill factor of 0.65.
