Abstract
Low dimensional perovskite materials, including two-dimensional (2D) and quasi-2D metal halide perovskites have attracted enormous interest due to their better stability and bandgap tunability compared to traditional three-dimensional (3D) perovskite materials. 2D/quasi-2D perovskite materials have been widely used in various fields, such as perovskite solar cells (PSCs), perovskite light-emitting diodes (PeLEDs) and perovskite transistors. Despite the research works on low dimensional perovskite applications which increased dramatically in last ten years, the investigations on stability and degradation mechanism of these materials are still lacking.
This work investigates the stability of low dimensional Ruddlesden-Popper (RP) perovskites and employs stable organic spacer candidates with great optoelectronic properties in light-emitting films and quasi-2D perovskite solar cells. The unstable 2D perovskites are used to produce valuable chemicals and microplastics conversion according to different degradation processes dominated by bromide and iodide. This work offers new insights into the study of low dimensional RP perovskites stability, proposing novel strategies for their application in photovoltaic devices, organic synthesis and microplastics degradation.
