【 摘 要 】

Fabrication of Cu/TiO2nanocomposite had been successfully performed. A nanocomposite was prepared by the insertion of metal (copper) in the TiO2nanoparticles. Cu/TiO2nanocomposite was deposited on the FTO glass used the spin coating method. Layers of Cu/TiO2nanocomposite were prepared in variations at 1, 2 and 3 layers. Spektrofotometer UV-VIS Lamda 25 was used to determine the optical characteristics and the energy gap of DSSC materials. El kahfi 100/I-V Meter and Keithley 2602A was used to determine the electrical properties of Cu/TiO2nanocomposite. UV-VIS result was showed that there increased absorption wavelength of Cu/TiO2nanocomposite and were able to decrease the energy gap. El kahfi was showed that the conductivity of the Cu/TiO2nanocomposite was 3.71x10-2(ω-1m-1). Keithley was showed that the highest efficiency in the 3 layers of Cu/TiO2nanocomposite of 0.011%.
