碩士 === 大葉大學 === 工業工程與管理學系 === 103 === This study can be divided into two parts. In the first part, In spin coating method graphene suspension was uniformly dispersed onto Corning 1737 glass, Preparation of the conductive film: Then by electrophoresis deposition method, compared the graphene deposited on ITO glass substrate. The catalytic through modified Hummers method, So more efficiently dispersed graphene in solution, The four-point probe in electrophoretic deposition of graphene way better than the effect of the spin coating method;Then using Hall Effect analyzed, The results show that the deposition parameters 10v60s best carrier concentration of 4.34 (× 1017cm-3). The second part is the electrophoretic deposition of graphene deposited on ITO substrate. As the dye-sensitized solar cell electrode, then replaces the platinum electrode, by controlling the voltage and time of the preparation to corresponding electrode. The working electrode layer is three TiO2, Its photoelectric conversion efficiency measured DSSC, The photoelectric conversion efficiency of DSSC measurements AM1.5 simulated solar light irradiated to the element results: 10v-60s deposition of electrodes is better, η% with increasing voltage and time, its efficiency will be a slight increase.
