Abstract: Resonant optical cavities incorporating black phosphorus to enable electrically tunable control of light are disclosed. Methods and devices are described that use black phosphorus as an electrically tunable optical material to control phase, amplitude and/or polarization of light from visible to mid-infrared wavelengths. The operating wavelength of the optical cavities depends on the thickness of the embedded black phosphorous. Tunable control of light is performed by adjusting the doping level of black phosphorous.

Abstract: Luminescent solar concentrators in accordance with various embodiments of the invention can be designed to minimize photon thermalization losses and incomplete light trapping using various components and techniques. Cadmium selenide core, cadmium sulfide shell (CdSe/CdS) quantum dot (“QD”) technology can be implemented in such devices to allow for near-unity QDs and sufficiently large Stokes shifts. Many embodiments of the invention include a luminescent solar concentrator that incorporates CdSe/CdS quantum dot luminophores. In further embodiments, anisotropic luminophore emission can be implemented through metasurface/plasmonic antenna coupling. In several embodiments, red-shifted luminophores are implemented. Additionally, top and bottom spectrally-selective filters, such as but not limited to selectively-reflective metasurface mirrors and polymeric stack filters, can be implemented to enhance the photon collection efficiency. In some embodiments, luminescent solar concentrator component is optically connected in tandem with a planar Si subcell, forming a micro-optical tandem luminescent solar concentrator.

Abstract: Luminescent solar concentrators having a grid-based PV design can be implemented in many different ways. In several embodiments, the LSC is implemented using infrared luminophore technology combined with a PV design implementing a grid of PV cells. LSCs can incorporate quantum dots that absorb uniformly across the visible spectrum and photoluminesce down-shifted energy light in the infrared wavelength regime. Some embodiments include PV cells utilizing micro-grid structures that can be implemented for scalable and controllably transparent applications, such as but not limited to power windows targeted for building integrated photovoltaic applications. In a number of embodiments, the LSCs can utilize a unique PV cell form factor and spectral filter coatings to increase the thermal insulation of the window and enhance photocurrent capture by a silicon micro-grid.

Abstract: Systems and methods in accordance with embodiments of the invention implement electrically tunable metasurfaces. In one embodiment, an electrically tunable metasurface reflectarray includes: a mirrored surface; a conductive layer; a dielectric layer; where the conductive layer and the dielectric layer are in direct contact, and thereby define a conductor-dielectric interface; a plurality of subwavelength antenna elements; and an electrical power source configured to establish a potential difference between at least one subwavelength antenna element and the mirrored surface; where a potential difference between a subwavelength antenna element and the mirrored surface applies an electric field to a corresponding region of the electrically tunable metasurface reflectarray; where any applied electric fields in conjunction with the geometry and the material composition of each of the subwavelength antenna elements, the conductive layer, and the dielectric layer, enable the electrically tunable metasurface reflectarray to measurably augment the propagation characteristics of incident electromagnetic waves.
