Characterizing Interfacial Structures of Dye-Sensitized Solar Cell Working Electrodes.

ABSTRACT: In this feature article, we discuss the fundamental use of materials-characterization methods that directly determine structural information on the dye···TiO₂ interface in dye-sensitized solar cells (DSCs). This interface is usually buried within the DSC and submerged in solvent and electrolyte, which renders such metrological work nontrivial. We will show how ex-situ X-ray reflectometry (XRR), atomic-force microscopy (AFM), grazing-incidence X-ray scattering (GIXS), pair-distribution-function analysis of X-ray diffraction data (gaPDF), and in-situ neutron reflectometry (NR) can be used to deliver specific structural information on the dye···TiO₂ interface regarding dye anchoring, dye aggregation, molecular dye orientation, intermole
