Vacuum chamber for in-operando grazing-incidence X-ray scattering experiments on novel thin-film solar cells — •Bernhard Kalis, Johannes Schlipf und Peter Müller-Buschbaum — TU München,Physik-Department, LS Funktionelle Materialien, James-Franck-Str. 1, 85748 Garching

In the past few years hybrid perovskite solar cells have reached power conversion efficiencies of about 20%. Alternatively, organic and other types of hybrid solar cells offer potentially cheap energy supply. The photovoltaic performance of these novel solar cell materials seems to be directly linked to the morphology of the solar cell film. To understand these connections between structural changes of the absorber material due to the influences of temperature and humidity in addition to the aging of the solar cell we use the grazing-incidence small and wide angle X-ray scattering (GISAXS/GIWAXS) method during operation [1]. To fulfil and control all these environmental influences, a newly designed vacuum chamber comes to action that consists of several modules to provide multi-functionality. This Chamber has also the ability to be pre calibrated in order to minimize the expenditure of time during a beam time at a synchrotron such as the ELETTRA in Trieste, Italy or the DESY in Hamburg, Germany.
