Abstract(in English) Dye-sensitized solar cells (DSSCs) made from nanostructured TiO_2 electrodes have received considerable attention as future solar cells. The surface morphology optimization of TiO_2 electrodes is one of the factors for improving the DSSCs efficiency. Recently, it was reported that TiO_2 nanotube electrodes show higher short-circuit current than TiO_2 nanoparticle electrodes. This phenomena can be possibly applied for DSSCs to increase photovoltaic conversion efficiency. In this paper, we fabricated the TiO_2 nanotube electrodes, and CdSe quantum dots (QDs) were adsorbed as a sensitizer instead of organic dye. We report the experimental results on optical absorption and electron transfer from CdSe QDs to TiO_2 electrodes by using the photoacoustic (PAS) and incident photon to current conversion efficiency (IPCE) methods, respectively.
