| Summary: | 碩士 === 國立雲林科技大學 === 電子工程系 === 105 === The counter electrode (CE) was prepared by mixing graphite and carbon black for dye-sensitized solar cells (DSSCs). The graphite and carbon black nanoparticles were mixed in anhydrous ethanol under stirring until uniform and obtained the carbon solution. Carbon solution was sprayed onto indium tin oxide (ITO) by using self-assembly spray coating. The first experimental stage, TiO2 was added in graphite solution to enhance adhering of the time on substrate and the solar cell conversion efficiency. The second experimental stage the large surface carbon black was added to enhance catalysis and short-circuit current density (Jsc) of the cell. The third experimental stage of the carbon film thickness was controlled by spraying time (3~20 seconds). The research results show that the carbon thin film thickness increased from 2.3 μm to 10.4 μm, the Jsc was increased from 4.7 mA/cm2 to 5.8 mA/cm2, and the photocurrent of dye-sensitized solar cell photovoltaic conversion efficiency (η%) was increased from 0.8% to 1.5%.
