摘要： The present disclosure relates to focusing luminescent concentrators wherein directional emission, obtained by placing an absorber/emitter within a microcavity or photonic crystal, may be oriented by a macroscopic concentrator and focused to a point or line for 3D or 2D concentration, respectively. The focusing luminescent concentrators disclosed herein may provide high concentration ratios without the need for tracking, and may reduce re-absorption losses associated with conventional concentrators. The present disclosure further relates to photovoltaic cells and/or optical detector devices comprising a focusing luminescent concentrator. The devices and methods presently disclosed are also useful, for example, in solar, thermal and thermophotovolatic applications.
