Abstract
Carbon-coated electrodes is superior substitution for platinum electrodes of Dye-Sensitized Solar Cells (DSSC). This paper describes effect of electrode coating methods as well as carbon types on the performance of DSSC. The electrodes were prepared using 3 methods, i.e. doctor blade, metering rod and bubble deposition. Commercial industrial-grade and medical-grade activated carbon were used in this research. The DSSC performance was measured from I-V curve and electrochemical impedance spectroscopy, meanwhile the morphology of coated carbon electrode was studied from Scanning Electron Microscope and Brunauer-Emmett-Teller analysis. It was found that efficiency of DSSC was higher when the counter electrodes were prepared using doctor blade and bubble deposition methods with medical-grade activated carbon. The highest achievement on light-to-electricity conversion was 3.76%.Keywords: carbon-based electrode, coating methods, performances of DSSC
