Use Of Cu-C-Tio2 In Dye Sensitized Solar Cell

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. I268722 I3 268722 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 microscopySEM and Fourier transform infrared FT-IR techniques.
