In-situ characterization of 2D hybrid perovskite under illumination

Layered hybrid metal halide perovskites are of increasing relevance for various optoelectronic applications, particularly for modern photovoltaics. The aim of this proposal is to gain detailed structural insight into the series of new layered hybrid metal halide perovskite materials incorporating photoactive organic components upon irradiation. We will determine their structural properties, the contribution of different phases, as well as the corresponding orientation relative to the conductive substrate, which is relevant to their application in optoelectronics. In addition, we will study the changes of their structural properties in response to UV light. The combined results from X-ray scattering and current-voltage measurements will reveal critical factors for their operation in functional devices for renewable energy conversion in photovoltaics.
