Excitonic Systems for Solar Energy Conversion


Case Study

The vision of this project is to develop smart concepts and novel, full-spectrum materials for next-generation low-cost, high efficiency, light-harvesting devices. 


Converting low energy “waste photons” into “high-value” high-energy photons would revolutionise the way we use solar energy and light in general. These concepts include the up- and down-conversion of photons to make more efficient use of the solar spectrum and drastically improve the efficiency of photon absorption, emission, exciton fission/fusion and light-induced charge separation processes across the visible and IR range.

Platform areas of work

  • Thin Film Upconversion Devices
  • Next Generation Luminescent Solar Concentrators
  • Solution Processed Next-Generation Photovoltaics


Develop novel, printable photovoltaic materials which can replace or complement traditional silicon, and create next-generation low-cost solar concentrators which can operate under diffuse sunlight. The team will also develop novel biomimetic systems that aim at converting sunlight directly into storable fuels.
