Abstract
Gold nanoparticles and silicate microsheet modified TiO2 photoanode with various decoration amount of gold solution have been successfully synthesized. The gold nanoparticles were prepared using Turkevich method and silicate microsheet was using silica gel. The sample were characterized by XRD, SEM, and FTIR. The DSSC performance were evaluated by photocurrent-voltage measurement. The results show the increasing decoration amount of gold nanoparticles, increase the intensity of diffraction peaks. The gold nanoparticles size is 20-35 nm. Comparing with pristine TiO2 photoanode, the efficiency of DSSC using modified photoanode increase up to 31%.
