Layered Hybrid Perovskites with Enhanced Functionalities for Photovoltaics

Layered hybrid perovskites have attracted considerable attention for various optoelectronic applications. However, they remain inferior in optoelectronic devices as compared to their 3D perovskite analogs due to the electronic inactivity of the organic components. The aim of this proposal is to obtain a detailed structural overview of the series of new layered hybrid perovskite materials with enhanced functionalities incorporating electro- and photoactive organic components. We will determine their structures, the contribution of different phases, as well as the corresponding orientation relative to the substrate. Furthermore, we will study their structural properties in response to light. The combined results from X-ray scattering and current-voltage measurements will enable unraveling the critical factors for their operation in functional devices for renewable energy conversion in photovoltaics.
