Photon recycling in heterojunction thin-film solar cells

Objective

The Helio-Carnot Club is investigating theoretically thin-film solar cell efficiencies. The idea is to obtain theoretical guidelines for the optimisation of these cells.


There is wide interest in Europe, notably in Germany, Belgium, France and the UK, in thin-film solar cells. Our collaboration, based on three of these countries, is analysing the heterojunction characteristics from a fundamental viewpoint. Thus phenomenological correction factors to all characteristics are interpreted in terms of more fundamental properties (eg recombination properties). In this way efficiency curves can be obtained as a function of energy gaps, surface and bulk recombination rates, band gap discontinuities, etc. Such curves indicate answers to design questions as to what has to be done to obtain the best efficiencies.
