Perovskite-based photoabsorbers have a low material criticality, a high light absorption capacity and can achieve specific optical properties by adjusting the chemical composition. This makes perovskites interesting for use in multi-junction solar cells: by stacking several perovskite solar cells with different band gaps, the efficiency can be significantly increased and exceed the theoretical maximum of single-junction solar cells.
In the "Perovskite Thin-Film Photovoltaics" research topic, we are working on the development of scalable manufacturing processes for perovskite solar cells and modules. The focus here is on low-temperature processes in which functional layers are deposited or printed from solution. This makes it possible to produce the components on flexible substrates in order to open up new fields of application - particularly in the area of integrated photovoltaics. We conduct our research at an international level and are a point of contact for industrial and academic players in the field of coating technology, cell production and system integration.
