摘要：

Dye-sensitized solar cell is fabricated using Rose Bengal dye (RB) for sensitization of nanocrystalline TiO2 and that imparts extension in spectral response towards visible region by modifying the semiconductor surface. Further, the photoresponse of the cell was evaluated by analyzing its J-V and impedance characteristics under illumination with metal halide light source of 400W with an incident light of 73 mW/cm(2). Various photovoltaic parameters like J(sc), V-oc, FF were evaluated and found to be 3.22 mA, 890 mV, 0.53, respectively, resulting conversion efficiency (eta) of 2.09%. Impedance analysis of the cell was carried out to investigate the internal resistance of the cell by recording Cole-Cole plots in between real and imaginary impedance in dark and with illumination under variable biasing, i.e. from 0 to 3 V.
