Abstract
We developed a new structure for the DSC comprised of metal substrates. Titanium was utilized for the TiO2/dye electrode. The platinum thin film with open stripes was prepared for the counter electrode. I-V characteristics for the present cell showed the similar performance to the cell together with the FTO substrate. The FF value was especially larger in the Ti-based cell than in the FTO-based cell.
The photovoltaic properties were not reduced in large amount even for six fold enlargement of the TiO2/dye electrode; the Js c and the FF decreased only to 70% and 85%, respectively. These results suggest that titanium could replace the metal oxide substrates especially in the large electrodes.
