Abstract (in Japanese) (See Japanese page) 
(in English) A counter electrode of dye-sensitized solar cells plays a significant role in the reduction of tri-iodide with electrolyte as a catalyst. Thus, the counter electrode of dye-sensitized solar cells is an important component, which often limits the cell performance. Some materials such as carbon, graphene, carbon nano-tube, transition metal and compounds, and polymer have been investigated as counter electrode materials. However, Pt is still the dominant counter electrode material despite its high cost. This work focused on a low-cost polymer as a counter electrode material of dye-sensitized solar cells. Poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) was applied for the counter electrode. As similar to previous studies on PEDOT:PSS counter electrode, initial photovoltaic performance of dye-sensitized solar cells based on PEDOT:PSS counter electrode was lower than that of Pt counter electrode. Especially, fill factor of dye-sensitized solar cells was significantly decreased from Pt to PEDOT:PSS counter electrodes. To improve the catalytic properties of polymer counter electrodes, this work introduced nanoparticles into polymer layer. Nanoparticle addition increased the surface area of polymer counter electrode and activated the catalytic reactions. Consequently, we have realized the dye-sensitized solar cells with the polymer nanocomposite counter electrode containing PEDOT:PSS and nanoparticles exhibiting higher efficiency and photocurrent than the dye-sensitized solar cells based on Pt counter electrode.
