A Dye Sensitized Solar Cell with ZnO-Coated TiO₂ Electrode and Carbon Nanotubes Electrode for High Power Conversion Efficiency

Abstract:

This study examines two things about a dye sensitized solar cell (DSSC) to improve power conversion efficiency. One is how to make ZnO-coated TiO2 electrode. The other is how to make carbon nanotube (CNT) electrode. First, we considered the process of making the ZnO-coated TiO₂ electrode of the DSSC. This ZnO coating of the DSSC is important for the increase of power conversion efficiency. The fabrication method of the ZnO-coated TiO₂ electrode was simple dip coating. This method uses the immerse of the zinc acetate dehydrate [Zn (CH₃COO₂)・2H₂O] solution. This method can make the cheap ZnO-coated TiO₂ electrode. However, this method has a slightly negative effect, which is filling in holes of the porous TiO₂ layer. We tried to improve this negative effect. We changed the concentration of a zinc acetate dehydrate solution from low to high. Also, we changed the immersing time of the zinc acetate dehydrate solution. We did the control of the band gap of ZnO-coated TiO₂ electrode of DSSC for increasing power conversion efficiency. Second, we substituted CNT for counter electrodes to improve the performance of DSSC. As a manufacture method of CNT electrode, we used electrophoretic deposition (EPD). After that, we baked this CNT electrode and measured its specific surface area. We tried to improve specific surface area by changing baking temperature.
