Abstract

CdSe-TiO ₂ nanocomposites were synthesized via aminolysis of Ti-oleate complexes in the presence of CdSe nanocrystals, and their application as sensitizers for TiO ₂ solar cells was investigated. The formation of CdSe-TiO ₂ nanocomposites was confirmed using transmission electron microscopy and Raman spectroscopy. The emission spectrum of CdSe-TiO ₂ nanocomposites revealed photoinduced charge separation at the CdSe- TiO ₂ interface of the composite. The photocurrent-voltage properties of CdSe-TiO ₂-sensitized TiO ₂ particle films compared favorably with those of CdSe-sensitized TiO ₂ films. Evidence was also found indicating that the TiO ₂ component of the composite protects CdSe against degradation during film annealing.
