Abstract EN
A double-layered photoanode made of hierarchical TiO2 nanotube arrays (TNT-arrays) as the overlayer and commercial-grade TiO2 nanoparticles (P25) as the underlayer is designed for dye-sensitized solar cells (DSSCs).
Crystallized free-standing TNT-arrays films are prepared by two-step anodization process.
For photovoltaic applications, DSSCs based on double-layered photoanodes produce a remarkably enhanced power conversion efficiency (PCE) of up to 6.32% compared with the DSSCs solely composed of TNT-arrays (5.18%) or nanoparticles (3.65%) with a similar thickness (24 μm) at a constant irradiation of 100 mW cm−2.
This is mainly attributed to the fast charge transport paths and superior light-scattering ability of TNT-arrays overlayer and good electronic contact with F-doped tin oxide (FTO) glass provided from P25 nanoparticles as a bonding layer.
