Mie-Metamaterials-Based Thermal Emitter for Near-Field Thermophotovoltaic Systems
In this work, we theoretically analyze the performance characteristics of a near-field thermophotovoltaic system consisting a Mie-metamaterial emitter and GaSb-based photovoltaic cell at separations less than the thermal wavelength. The emitter consists of a tungsten nanoparticle-embedded thin film of SiO 2 deposited on bulk tungsten. Numerical results presented here are obtained using formulae...
متن کاملFabrication of an Omnidirectional 2D Photonic Crystal Emitter for Thermophotovoltaics
In a thermophotovoltaic (TPV) system, a heat source brings an emitter to incandescence and the spectrally confined thermal radiation is converted to electricity by a low-bandgap photovoltaic (PV) cell. Efficiency is dominated by the emitter’s ratio of in-band emissivity (convertible by the PV cell) to out-of-band emissivity (inconvertible). Two-dimensional photonic crystals (PhCs) offer high in...
متن کاملAn integrated microcombustor and photonic crystal emitter for thermophotovoltaics
Thermophotovoltaic (TPV) energy conversion is appealing for portable millimeterscale generators because of its simplicity, but it relies on a high temperatures. The performance and reliability of the high-temperature components, a microcombustor and a photonic crystal emitter, has proven challenging because they are subjected to 1000–1200◦C and stresses arising from thermal expansion mismatches...
متن کاملHIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS
Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...
