Research Abstract

To increase the quantum efficiency of the dye sensitized solar cells (DSC), I developed DSC using nanostructured electrodes to increase in the excitation of the dressed-photon and phonon. By using TiO2 nanoparticles and ZnO nanorod structure with the controlling the size and shaped, large increase in incident photon to current conversion efficiency (IPCE) was achieved, indicating the energy up-conversion was achieved by the dressed-photon and phonon-assisted effect.
