| 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. |
