The stability of perovskite solar cells is still an unresolved issue and must be addressed for making perovskites a valid option for industrial products, e.g. in the form of enhancing the performance of silicon solar cells in tandem cells. As an initial step for the systematic investigation of structural changes, it is therefore beneficial to enable us to track structural changes within hybrid perovskite thin films. Furthermore, we would like to have the ability to determine the dynamics of such changes as well as the responsible driving forces.
We are using in-situ time-resolved x-ray scattering to resolve structural changes that active layers of hybrid perovskite solar cells undergo during processing [1,2] and conditions necessary for operation. Systematically examining the resulting structural changes while deliberately accelerating the ageing process [3] can help on the route to discover options that help to suppress these structural changes in the end.
