Energie et thermoelectricite
The interactions between the environment and excitons generated by light harvesting in photosynthetic pigment-protein complexes (PPC) is a key part of the remarkable, often close to 100%, quantum efficiency of solar energy transduction in natural photosynthesis. The environmental fluctuations spectra in PPCs are known to be have significant frequency structure, including strong contributions...

Energie et thermoelectricite
Carrier-multiplication (CM) is a process in which more than one electron-hole pair is created as the result of the absorption of a single photon. CM in semiconductor quantum dots (QDs) has recently received considerable attention both experimentally and theoretically. But the results are subjects of important controversies and therefore it is still not clear whether CM in QDs has the potential...

Energie et thermoelectricite
Because of the weakness of van der Waals inter-molecular bonds, organic semiconductors are commonly believed to stand in an intermediate region between the molecular limit and the extended band picture, calling for concepts that go beyond the standard paradigms of inorganic semiconductors. Experimental charge transport and optical studies of organic semiconductors over the past few years have...

Energie et thermoelectricite
Several novel types of nanostructured materials are emerging as potentially suitable for the development of high ZT thermoelectrics. Amongst them, Nanoparticle Embedded in Alloy Thermoelectric (NEAT) materials, offer a good opportunity for theoretical computations to predict thermoelectric properties and compare with experimental results.
In this talk I will first discuss the theoretical...
