Fortification of CdSe Quantum Dots with Graphene Oxide. Excited State Interactions and Light Energy Conversion
Graphene based 2-D carbon nanostructures provide new
opportunities
to fortify semiconductor based light harvesting assemblies. Electron
and energy transfer rates from photoexcited CdSe colloidal quantum
dots (QDs) to graphene oxide (GO) and reduced graphene oxide (RGO)
were isolated by analysis of excited state deactivation lifetimes
as a function of degree of oxidation and charging in (R)GO. Apparent
rate constants for energy and electron transfer determined for CdSe–GO
composites were 5.5 × 10<sup>8</sup> and 6.7 × 10<sup>8</sup> s<sup>–1</sup>, respectively. Additionally, incorporation
of GO in colloidal CdSe QD films deposited on conducting glass electrodes
was found to enhance the charge separation and electron conduction
through the QD film, thus allowing three-dimensional sensitization.
Photoanodes assembled from CdSe–graphene composites
in quantum dot sensitized solar cells display improved photocurrent
response (∼150%) over those prepared without GO
