| Abstract Scope |
Two-dimensional (2D) layered materials range in composition from mono-elemental systems such as graphene and black phosphorus, binary transition-metal dichalcogenides (TMDCs) such as WSe2, as well as multi-component organo-halide perovskites. In this talk, we discuss our efforts in examining the light-matter interactions of a wide range of 2D materials, including black phosphorus and Ruddlesden-Popper perovskites. These two material systems show direct optical transitions in the bulk, unlike in many of the semiconducting transition metal dichalcogenides, where direct optical transitions are evident in the monolayer limit. Despite their enhanced light-matter interactions, these materials are also vulnerable to oxygen and moisture. In this work, we discuss our approaches to stabilize black phosphorus for electronic and optoelectronic devices on flexible and compliant substrates using low-cost, additive manufacturing techniques. We also present our recent work to address stability issues in the organo-halide perovskites through compositional engineering and collector meta selection within the solar cell stack. |
