Abstract for Presentation
Molecularly Engineered Interfaces in Metal Halide Perovskite Solar Cells
Over the past decade, organic-inorganic hybrid perovskites have emerged as a new class of solution processable semiconductor for many optoelectronic applications, such as solar cells and light emitting devices. Their electronic, electrical and optical properties can be controlled by tuning their compositions and crystal structures. In this talk, I will discuss how to control the dimension and nanostructure of perovskites by introducing small molecules with tailored functional groups that can strongly interact with the perovskite crystals. Using such strategy, we have developed very stable quasi-2D perovskite films with tunable interfacial electronic structures and the corresponding solar cells show much improved stability and efficiency [1-2] . I will also discuss how to lean on the experience in interface engineering for organic solar cells and design new electron and hole transport conjugated materials with proper interfacial properties to provide surface defeat passivation functionality and improve the charge collection efficiency of perovskite solar cells [3-4] , as well as organic/perovskite tandem solar cells.
