Özet
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 degrees 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.
