“…Erbium oxide is well suited to TPV as its spectral peak appears at 1.54 μm (0.81 eV), slightly higher than the band gaps of Ge and GaSb. Several host materials and fabrication methods have been studied . A common early TPV emitter design is the mantle, a cylindrical or slightly conical structure named after the gas lantern component that it resembles, which allows for radial emission of photons.…”

Applying thermophotovoltaic (TPV) technologies to existing energy generators allows us to increase energy output while utilizing present infrastructure by reclaiming the heat lost during the production process. In order to maximize the efficiency of these sources, the conversion efficiency of the TPV system needs to be optimized. Selective emitters are often used to tailor the spectrum of incident light on the diode, blocking any undesirable light that may lead to device heating or recombination. Over the years, many different technologies have been researched to create an ideal selective emitter. Plasmas and rare‐earth emitters provided highly selective spectra early on, but their fixed peaks required tailoring the diode's band gap to the emitter's characteristic wavelength. Recent advances in engineerable materials, such as photonic crystals and metamaterials, allow the opposite to take place; an appropriate selective emitter can be designed to match the TPV diode, allowing the diode structure to be optimized independently from the emitter.

“…Rare earth material has a strong ability to absorb light and its emission spectrum is narrow. These advantages determine that it can be an emitter of a thermal PV system [6]. In 1972, Guazzoni et [7] reported high temperature emission spectrum of erbium, samarium, neodymium, ytterbium and other rare earth oxide ceramics [7].…”

Abstract:The optical properties of one-dimensional photonic crystals with Er 2 O 3 /Si structure are designed and calculated by Finite-Difference Time-Domain method. The influence of different thickness and reflectivity on the radiation properties were studied. It was found that the radiation spectral intensity at high temperatures was drastically reduced near the wavelength of 1.8 μm for a 40% Er 2 O 3 + 60% Al 2 O 3 sample due to the strong oscillations of the reflectance.

“…A TPV device uses an emitter, which is heated up by various energy sources to high temperatures, as a source of radiation for photovoltaic energy conversion. That means a large amount of unusable electromagnetic radiation impinges on the photovoltaic cell (PV) [2,5]. So, the enhancement of TPV efficiency can be achieved by using selective emitters which are characterized by strong emission at certain wavelengths [5].…”

The development of selective emitters is very important for energy conversion and photonic systems, such as thermophotovoltaic (TPV) [6][7], solar cells [8][9] and photodetectors [10].…”
