Controlling ion and electron transport in hybrid perovskites confined in mesoporous matrices (B03)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Analytical Chemistry
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492723217

The project (Grüninger/Herzig) investigates ion and electron transport in hybrid lead halide perovskites confined in mesoporous matrices as a function of pore size and geometry, and interface interactions. External electric fields are used to trigger ion and electron transport in the structured composites and the transport pathways will be analyzed in-situ to yield structural and dynamical information locally and globally. Through the transition from bulk transport to transport in systematically restricted nanopores, and associated interfaces, we expect to understand and separate ion and electron transport.
