T1  - Modeling the time-dependent characteristics of perovskite solar cells
N2  - We proposed two different time-dependent modeling approaches for variation of device characteristics of perovskite solar cells under stress conditions. The first approach follows Sah-Noyce-Shockley (SNS) model based on Shockley–Read–Hall recombination/generation across the depletion width of pn junction and the second approach is based on thermionic emission model for Schottky diodes. The connecting point of these approaches to time variation is the time-dependent defect generation in depletion width (W) of the junction. We have fitted the two models with experimental data reported in the literature to perovskite solar cell and found out that each model has a superior explanation for degradation of device metrics e.g. current density and efficiency by time under stress conditions. Nevertheless, the Sah-Noyce-Shockley model is more reliable than thermionic emission at least for solar cells.

N2  - The Bauhaus Summer School series provides an international forum for an exchange of methods and skills related to the interaction between different disciplines of modern engineering science.
The 2012 civil engineering course was held in August over two weeks at Bauhaus-Universität Weimar. The overall aim was the exchange
of research and modern scientific approaches in the field of model validation and simulation between well-known experts acting as lecturers
and active students. Besides these educational intentions the social and cultural component of the meeting has been in the focus. 48 graduate and doctoral students from 20 different countries and 22 lecturers from 12 countries attended this summer school. Among
other aspects, this activity can be considered successful as it raised the
sensitivity towards both the significance of research in civil engineering
and the role of intercultural exchange.
This volume summarizes and publishes some of the results: abstracts
of key note papers presented by the experts and selected student
research works. The overview reflects the quality of this summer school.
Furthermore the individual contributions confirm that for active students
this event has been a research forum and a special opportunity
to learn from the experiences of the researchers in terms of methodology
and strategies for research implementation in their current work.
