Abstract
The paper reviews recent results on electrochemical methods applied to the determination of the density of electronic states in several components of advanced nanostructured devices such as the dye solar cell (Grätzel cell), switchable displays, and sensors. We discuss the application of cyclic voltammetry and impedance spectroscopy to determine the chemical capacitance of mesoporous metal-oxide semiconductors (mainly TiO2), organic hole transport materials, and molecular functionalizing elements.
Graphical abstractLinear voltammetry shows the shift of the density of electronic states in a nanostructured TiO2 film by adsorption of dipolar molecules in the metal oxide surface.Figure optionsDownload full-size imageDownload as PowerPoint slide
