Abstract :
In this paper, we had fabricated a flexible DSSC with the PET-ITO substrate for photo electrode, and the conversion efficiency of flexible DSSC was 2.27%. The efficiency enhancement of DSSCs with the Ti-deposited thin film had also demonstrated on StSt/SiOx/ITO substrate. A dense Ti thin film between StSt/SiOx/ITO and porous TiO2 interface with low contact resistance can increase the electron conduction and suppresses the interfacial electrons recombination. In addition, after using Ti thin-film as an interfacial layer between PET/ITO and porous TiO2, the photovoltaic characteristics were improved. Furthermore, the Ti thin-film can apply on many kinds of substrates for DSSCs, such as glass, stainless steel (StSt), and plastic for more various applications.
