Investigations Of Ti02-Cu20 Composite Treated With Different Sintering Temperature As Photoanode

The efficiency of low-cost dye-sensitized solar cells (DSSCs) was increased by doping Cu20 into TiO2 photoanode pastes a various compositions. For compositional evaluation, the materials were characterised using X-ray diffraction (XRD). The crystallite size of the Cu20-TiO2 composite at 2%, 4%, 6%, and 8% was estimated using Scherer's method and found to be 490.95nm, 376.03nm, 379.21 nm, and 342.58nm, respectively. Cu2O doping of TiO2 resulted in a reduction in the crystallite size. X-ray diffraction also verified the anatase phase of Cu20-doped TiO2. After sintered at 300°C, 350°C, and 400°C, the doping samples were evaluated using a UV-Vis Spectrometer. . The photo-sensitizers were derived from P.Beile and characterized using UV-Vis Spectrometer and FT-1R The TiO2-Cu2O thin film were characterized using UV-V1S. Thin layer of Cu20-TiO2 paste is applied on translucent conductive ITO covered glass using a doctor-blade technique with an average crystallite size roughly 397.19 nm. All the photovoltaic parameter were recorded and discussed.
