Yes / The application of photoelectrochemical methods presents the researcher with a powerful set
of versatile tools by which photoactive materials, such as semiconductor quantum dots, at
conductive interfaces may be interrogated. While the range of photoelectrochemical
techniques available is quite large, it is surprising that very few have found their way into
common usage within the nanoparticle community. Here a number of photoelectrochemical
techniques and the principles upon which they are based are introduced. A short discussion
on the criticality of ensuring the nanoparticles are reliably anchored to the substrate is
followed by an introduction to the basic set of equipment required in order to enable the
investigator to undertake such experiments. Subsequently the four techniques of transient
photocurrent response to square wave illumination, photocurrent spectroscopy, intensity
modulated photocurrent spectroscopy (IMPS) and intensity modulated photovoltage
spectroscopy (IMVS) are introduced. Finally, the information that can be acquired using such
techniques is provided with emphasis being placed on a number of case studies exemplifying
the application of photoelectrochemical techniques to nanoparticles at interfaces, in particular
optically transparent electrodes.
