Abstract

In this study, we explore the use of various ratios of TiO₂ nanoparticle (NP)/nanowire (NW) composite films in back-illuminated dye-sensitized solar cells (DSSCs) based on cobalt redox couples. TiO₂ NPs provided sufficient surface areas for dye adsorption and TiO₂ NWs helped efficient charge transport in NP/NW composite film. Furthermore, incorporation of NWs in TiO₂ film makes it more porous, relaxing the limited mass transport of cobalt redox ions. As a result, DSSCs with proper weight percentage of NW incorporated TiO₂ NP/NW composite film showed a superior photovoltaic performance to DSSCs with pure TiO₂ NPs film.
