Optoelectronic Analysis of Spectrally Selective Nanophotonic Metafilm Cell for Thermophotovoltaic Energy Conversion
Qing Ni, Payam Sabbaghi, Liping Wang
This work theoretically explores a spectrally selective TPV cell based on an asymmetric Fabry-Perot resonance cavity structure with sub-100-nm GaSb layer. The simulated spectral pr…
Enhancing Solar Thermal Energy Conversion with Silicon-cored Tungsten Nanowire Selective Metamaterial Absorbers
Jui-Yung Chang, Sydney Taylor, Ryan McBurney +4
This work experimentally studies silicon-cored tungsten nanowire selective metamaterial absorber to enhance solar-thermal energy harvesting, simply fabricated by conformally coatin…
Near-Field Thermophotovoltaic Energy Conversion with Thin-film Tandem Cells
Payam Sabbaghi, Qing Ni, Liping Wang
The performance of a near-field thermophotovoltaic system with a tandem-cell structure composed of thin-film p-doped GaSb and n-doped InAs sub-cells on a gold backside reflector is…
Enhanced Infrared Emission by Thermally Switching the Excitation of Magnetic Polariton with Scalable Microstructured VO2 Metasurfaces
Linshuang Long, Sydney Taylor, Liping Wang
Dynamic radiative cooling attracts fast-increasing interest due to its adaptability to changing environment and promises for more energy-savings than the static counterpart. Here w…
Spectrally-Selective Vanadium Dioxide Based Tunable Metafilm Emitter for Dynamic Radiative Cooling
Sydney Taylor, Ryan McBurney, Linshuang Long +3
Dynamic radiative cooling with variable emissive power is experimentally demonstrated in this study by a wavelength-selective tunable metafilm emitter, which consists of an opaque…
