Our mission

To apply thermodynamic principles for developing new frequency-conversion methods. This will allow:

  •  Converting inefficient parts of the solar spectrum to wavelengths most efficient for energy-harvesting.
  •  Conversion of thermal energy to electricity.
  •  Efficient energy storage.
  •  Efficient high power light sources fully integrated on-chip lasers.
About us

We work with Excitonics. localized energy states in small molecules. By engineering the energy dynamics between Excitonics we bring the device functionality into the single molecule level.

Our group is highly multidisciplinary working at the interface between Physics, Thermodynamic, Optics, Materials, and Devices.
Excellent students and researchers in these areas are welcome to contact me.
