Recent Research Interest
In one focused avenue of interest with regard to solar energy conversion, the team is working on developing practical dye-sensitized cells, in which a layer of light-absorbing species (or material) is adsorbed onto a high surface area, nanocrystalline metal oxide semiconductor such as TiO2. This is typically sensitized to the terrestrial solar spectrum with a "Ru-trisbipy" or similar dye, however recent work has also addressed the use of inorganic semiconductors as sensitizers. These materials inject electrons into the metal oxide semiconductors upon illumination. The complete device is made by filling the porous voids of the sensitized oxide with a non-volatile material that acts as a hole transporter. This can be, for instance, a polymer based on a common hole-transport moiety such as triphenlamine, which is potentially doped with an ionic species or even a p-type semiconductor.
