In this work, we made network TiO 2 nanowires of high surface area, using the seeded growth process. An overall solar photoconversion efficiency of 8.51% has been achieved from the film including TiO 2 network nanowires, which is much higher than 6.94% of TiO 2 nanoparticulate film with same thickness (6.2 μm).
In the present work, we describe a practical technique to construct double-layer organized mesoporous TiO2 films with a combined thickness of 0.85 μm. Large mesopores (25.74 nm) formed in the film by using ovalbumin as the main template facilitate entry and adsorption of dye molecules. The films were sensitized by a dye that exhibits a high molar extinction coefficient because it contains a ligand with a fused-ring system. The double-layer films exhibited a solar conversion efficiency of 7.37%, which was about 35% higher than that of monolayer films.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
