Abstract:
To optimize materials that are used in photovoltaic applications — in particular for third generation solar cells — realistic continuum models are sought that can lead to a more efficient approach for finding improved growth parameters. The usual trial and error approach has lead to many good results, mostly however with the downside that many experiments had to be carried out for that end. Fundamental knowledge has to be united to derive realistic models that allow for a fast simulation. Eventually this can lead to a reduction of the number of experiments by supporting the work with optimized growth parameters. In this talk a model for Stranksi-Krastanov growth of quantum dots is presented, a small-slope approximation is carried out, pseudospectral methods with various time-stepping possibilities are introduced and numerical results are presented. In the last part of the presentation ongoing challenges are discussed, i.e. the dewetting of thin silicon films during annealing and grain growth.
