Confined Hybrid Perovskites

Within the CRC 1585 "MultiTrans"  our Project (B03) investigates ion and electron transport in hybrid lead halide perovskites spatially confined in mesoporous host matrices (SiO2, TiO2/SnO2) as a function of confinement strength, i.e., pore size, geometry and confinement-induced interface interactions. The transition from bulk transport to transport in systematically, spatially restricted nanopores, and associated interfaces, will allow for understanding and separating ion and electron transport pathways. External electric fields are used to trigger the ion and electron transport in the structured composite materials. The structural response and thus the transport pathways will then be analysed using in-situ solid-state NMR/NQR spectroscopy and X-ray methods, complementary analysis tools to yield structural and dynamical information on the local and global scale.

This is a joint project with the Herzig-group in Experimental Physics. In our group we focus on the synthesis of the composite materials via nanocasting of the perovskites into mesoporous matrices, their characterization using a range of methods, as well as in-situ characterization of ion and electron transport using solid-state NMR spectroscopy under an applied external electric field to trigger and direct ion and electron transport in the materials.
