We design and simulate dynamically tunable metasurfaces comprised of vanadium dioxide Huygens source nanoantennas. Simulations demonstrate metasurfaces capable of transmittance, reflectance, and absorbance modulation of >85%, with experimental realization in progress.
A new modular, hybrid solar power system is designed to generate both electrical and thermal energy by utilizing the full solar spectrum. The key element, an infrared-transparent concentrator photovoltaic (CPV) module, acts as a spectrum splitter, dividing solar radiation into two parts. The ultraviolet and visible light (“in-band”) are converted to electricity with high efficiency in CPV cells, while...
We design and simulate metasurfaces capable of inducing anomalous refraction with efficiency as high as 90%. Metasurfaces are designed for incident wavelengths spanning λ = 378nm to λ = 1340nm; a composite stacked metasurface capable of spectrum splitting is demonstrated.
A spectrum splitting, transmissive concentrating photovoltaic (tCPV) module is proposed and designed for a hybrid photovoltaic-solar thermal (PV/T) system. By utilizing III–V triple junction solar cells with bandgaps of 2.1eV/1.7eV/1.4eV, ultraviolet (UV) and visible light will be absorbed and converted to electricity, while infrared (IR) light will pass through and be captured by a solar thermal...
A new scalable, modular hybrid solar power system is designed to generate electricity through two pathways, CPV and CSP, in order to better meet grid energy demands for reliable renewable energy. The key element, a transmissive, spectrum-splitting multi-junction solar module, is modeled and simulated to analyze its electrical, optical, and thermal properties. Optimized designs are proposed to deliver...
