Preparation of composite-layered structure of TiO2 nanoparticles/TiO2 nanotubes and its role in dye sensitized solar cell

Composite layered structure of TiO 2 nanoparticles (TiNPs) and TiO 2 nanotubes (TiNTs) was prepared by two-step anodizing of titanium at 50 V to form well-aligned TiNTs with uniform diameter, followed by spin coating the TiNPs of 10–30 nm prepared by hydrothermal synthesis. For smaller number of cyc...
