Semiconductor-based selective emitter with sharp cutoff for thermophotovoltaic energy conversion
Qing Ni, Rajagopalan Ramesh, Cheng-An Chen +1
Semiconductor emitter can possibly achieve sharp cutoff wavelength due to its intrinsic bandgap absorption and almost zero sub-bandgap emission without doping. A germanium wafer ba…
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…
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…
Solar Thermal Energy Conversion Enhanced by Selective Metafilm Absorber under Multiple Solar Concentrations at High Temperatures
Hassan Alshehri, Qing Ni, Sydney Taylor +3
Concentrating solar power, particularly parabolic trough system with solar concentrations less than 50, requires spectrally selective solar absorbers that are thermally stable at h…
