From comparative studies of dye sensitized solar cell (DSSCs) fabricated using nanotubes (NTs) filled with nanoparticles (NPs) and empty NTs it is shown that filling of TiO2 NTs with NPs significantly increase efficiency of DSSCs. This increase depended on NT diameter and was found to be 17.4%, 55.6%, and 131% for solar cells with 40 nm, 80 nm, and 160 nm diameter NTs. The highest efficiency was observed for samples with 80 nm diameter NTs, which was 5.94% for ∼5 μm NT thickness DSSCs.
