abstract = {Climate change is one of the biggest problems in this
century. To reduce the emissions that lead to the climate
change, it is expected that renewable energy systems will
become very important for our energy supply in the future.
Among these renewable energies, photovoltaics (PV) belongs
to one of the fastest growing technologies. The key drivers
to justify an increasing share of photovoltaics in the
energy market are the reduction in cost, the increase of
efficiency and the increase in their reliability. Thin film
technologies have a share of the PV market of approximately
only $7\%.$ However, thin film technologies have many
advantages that show their potential for the future. Their
main advantages are their low costs and their promising
application for new markets, as for example for climate
zones with a high amount of diffuse irradiance or their
possibility to use them as building-integrated modules and
deposit them on flexible substrate. A big challenge for thin
film technologies is the energy yield prediction as thin
film solar cells exhibit metastabilities. To solve this
problem, dynamic performance models are necessary. In this
thesis, the performance of thin film solar cells and modules
are investigated and modeled under outdoor and laboratory
conditions, whereas two approaches of dynamic performance
models are implemented to improve the performance prediction
of thin film modules. At the beginning of this work, a
four-step procedure is defined to compare different
performance models with each other. The current-density
voltage (JV) curves of the outdoor modules are described
with the empirical Karmalkar-Haneefa (KH) performance model.
The KH model uses only four physical parameters, namely the
open circuit voltage (V$_{oc}$), the differential resistance
at the open circuit point (Roc), the short-circuit current
density (J$_{sc}$), and the differential conductance at the
short-circuit point (G$_{sc}$), to [...]},
