Abstract for Presentation
Photonics and energy applications of perovskite devices
Perovskite materials have been widely used in photonic applications because of their facile manufacture and excellent optoelectronic performance, including high optical absorption for solar cells, high color purity and spectral stability for lightemitting diodes, large Stokes shift or small absorption-emission overlap (low reabsorption loss) for luminescent solar concentrators, to name a few. Recently, perovskites have been adopted for energy harvesting applications because of their large piezoelectric coefficients. In this talk, I will present the latest progress in perovskite research ranging from photonics to energy-related applications [1-10]. The research discoveries include efficient solar cells based on monolayer perovskite bridges that enabled strong quantum dot coupling; bright, narrowband, and stable blue emitting perovskite diodes enabled by chloride insertion-immobilization; attachable luminescent solar concentrators; and high-performance nanogenerators based on perovskite materials.
