Thin film solar cells hold immense promise for space applications due to their lightweight and flexible nature, making them ideal for powering satellites and spacecraft. Understanding their performance under extreme conditions is pivotal for their successful deployment in space missions. This study introduces an experimental setup designed for operando grazing-incidence wide-angle X-ray scattering (GIWAXS) and grazing-incidence small-angle X-ray scattering (GISAXS) measurements on perovskite and organic thin film solar cells. The setup enables rapid temperature changes, simulating a wide range of operational environments. Crucially, the apparatus exposes solar cells to simulated sunlight of changeable intensity, facilitating measurements under realistic light conditions. Furthermore, it allows modulation of complete day-night cycles, adjusting both, light intensity and temperature up to 130 degrees Celsius to replicate dynamic environmental fluctuations. This methodology offers a comprehensive approach for dynamically evaluating thin film solar cells, providing insights into their structural and functional characteristics under diverse environmental conditions.
