Abstract
ZnO–TiO2 heterojunction photoanodes consisting of nanoparticles, nanorods, nanopropellers, and nanohedgehogs for dye-sensitized solar cell were first synthesized by one-step hydrothermal method technique on an indium tin oxide substrate at different temperatures (100–180°C) in a solution containing ZnCl2, TiCl4, ethanol and HCl. Furthermore, Sb2S3 quantum dots were grown on nanostructured ZnO–TiO2 surfaces by successive ionic layer adsorption and reaction. The photoelectrochemical performance data show that the dye-sensitized solar cells deposited on a quantum dot ZnO–TiO2 have a power conversion efficiency of 1.82% for nanoparticles, 3.00% for nanorods, 7.05% for nanopropellers, and 9.22% for nanohedgehogs. Because of its high power conversion efficiency, nanohedgehogs can be taken into account as a significant step in the development of solar cell performance for quantum-dot-sensitized solar cells.
