Theory

Introduction to stochastic thermodynamics: application to thermo- and photo-electricity in small devices part 1
Prof dr. M. Esposito (Université Libre de Bruxelles - ULB (BE)). His lecture starts with a simple introduction to the theory of stochastic thermodynamics. The aim is to demonstrate that a consistent nonequilibrium thermodynamic description can be constructed for small systems described by stochastic master equations. Later on it is shown that this formulation can be succesfully applied to study thermoelectricity and photoelectricity. The lector analyses in detail two simple models and special attention will be given to the study of efficiency at maximum power.

Device physics and simulation of organic solar cells
Prof. dr. ing. Thomas Kirchartz - Forschungszentrum Jülich (DE) first gives an overview of the general functionality of organic solar cells to show what can be simulated. He focuses then on how charge carrier extraction works on very thin devices. This involves understanding the recombination and measuring of the band diagram: how it looks and learn about it.
