In my Master’s thesis I worked with PID (Potential Induced Degradation) and had to read about solar cells and materials. I had to test 8 differently manufactured CIGS (Copper Indium Gallium Selenide) solar cells for PID in a climate chamber and compare it with Negative bias tests, Accelerated stability tests, temperature dependent tests and compare the degradation pattern. In this test I ended up finding that production conditions and process methods also play an important role in the degradation.

There was a close relation between these degradations. During this thesis I had to work with analysing techniques like IV, CV and Doping curves analyser, Thermography for DLIT, EQE measurements, Electroluminescence and Photoluminescence, oven for temperature induced stress and climate chamber with temperature and humidity control for PID with electric potential across the solar cells.

My stay in Ulm helped me to experience the German work atmosphere along with other activities in this small and happening city. Since there are not many researchers in this field and the novelty of the project, it was really interesting to work in a hot research topic with different companies' solar cells.
