The groups’ focus is Molecular Engineering of Functional Materials for Photovolatic and Light emitting applications. In the field of molecular-based photovoltaic devices, dye-sensitized solar cells (DSCs) have reached an efficiency of over 13%. This efficiency level, coupled with the use of inexpensive materials and processing has stimulated momentum to industrialize this technology. In these cells, the sensitizer, located at the junction between electron and hole transporting phases, absorbs sunlight and injects an electron and a hole into the n- and p-type materials, respectively. The former is an inorganic n-type wide bandgap oxide semiconductor (typically TiO2 anatase) and the latter is a liquid electrolyte or p-type hole transporter. The generated free charge carriers, travel through the nanostructured oxide to be collected as current at the external contacts. The significant advantage of DSCs is that they achieve the separation of light harvesting, and charge carrier transport, thus the maximum power point is virtually independent of light level therefore useful in all climate conditions. The general losses in dye-sensitized solar cells are due to the lack of sensitizer absorption in the near IR region, and the loss-in-potential from the optical band gap to the open-circuit voltage. The goal of the group is to engineer at molecular level novel panchromatic sensitizers and functionalized hole-transporting materials to achieve power conversion efficiency over 20%.
