Abstract: A novel and simple strategy has been used for the preparation of TiO2 nanoparticles co-doped with carbon (non-metal) and copper (transition metal) by sol-gel method. The dye sensitized solar cell was fabricated with Cu-C-TiO2 nanocrystalline layer on FTO conductive glass, sensitized with rhodamine B dye. I− / I3 − redox couple was used as liquid electrolyte and carbon (graphite) as counter electrode. The experimental results of rhodamine B sensitized Cu-C-doped TiO2 showed Voc= 101.2 mV, isc= 0.0545 mA, Vpp= 55.9 mV andipp= 0.0496 mA and FF = 0.50. The photo-to-electric power conversion efficiency was 0.004% under 66.0 mWcm-2 light intensity. The undoped andCu-C-TiO2 nanoparticles were analyzed by X-ray diffraction (XRD), scanning electron microscopy(SEM) and Fourier transform infrared (FT-IR) techniques.
