Functionalized electrophoretic deposition of CdSe quantum dots onto TiO2 electrode for photovoltaic application
We discuss about the utilization of functionalized electrophoretic deposition technique for photovoltaic application encompassing the prospective potential of both functionalization and electrophoretic deposition. We report the fabrication of TiO2 sensitized electrode by electrophoretic deposition of CdSe quantum dots. This method holds the advantage of achieving effective coating of CdSe onto TiO2 electrode by reducing the deposition time to 15 min. Cross-sectional and depth profile elemental analysis revealed the even distribution of CdSe across the TiO2 layer. Ninety percentage of light harvesting efficiency was achieved for the CdSe sensitized electrode affirming the efficacy of sensitization by functionalized electrophoretic deposition.
