Fabrication 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 کاملMetamaterial thermal emitters based on nanowire cavities for high-efficiency thermophotovoltaics
Metamaterial thermal emitters based on gold nanowire cavities on a gold substrate are designed to achieve a narrowband emission spectrum with the emission peak located slightly above the bandgap of photovoltaic (PV) cells, in order to improve the overall efficiency of thermophotovoltaic (TPV) systems. The metamaterial emitter made of gold nanowires embedded in an alumina host exhibits an effect...
متن کاملTemplate-Stripped Plasmonic Films for Thermophotovoltaics
Summary: Template stripping is a simple and versatile process for creating smooth patterned films from various materials. We will discuss improved plasmonic performance for template-stripped metals and their use in thermophotovoltaic applications. Introduction: Template stripping utilizes the fact that coinage metals (e.g., silver, gold, and copper) will wet certain substrates but adhere poorly...
متن کاملSurface Energy Anisotropy of SrTiO3 at 1400°C in Air
Geometric and crystallographic measurements of grainboundary thermal grooves and surface faceting behavior as a function of orientation have been used to determine the surface energy anisotropy of SrTiO3 at 1400°C in air. Under these conditions, thermal grooves are formed by surface diffusion. The surface energy anisotropy was determined using the capillarity vector reconstruction method under ...
