Abstract

By applying diffuse reflectance transient absorption spectroscopy to dye-sensitized solar cells under operational conditions, we were able to directly correlate interfacial electron injection kinetics from a Ru complex sensitizer to a TiO(2) nanocrystalline electrode with the incident photon to current efficiency values. It was revealed that ionic liquid electrolytes reduced the initial electron injection efficiency by suppression of the approximately 100 ps process.
