“…In the previous work [8], the authors proposed the super-adiabatic combustion TPV system. In this system, the porous quartz glass plates played significant roles on the heat storage for the energy recirculation and the filtration of the long-wavelength components that were absorbed and were regenerated into enthalpy increase in the mixture.…”

Electric power was obtained using the super-adiabatic combustion TPV power generation system. In the system, a porous emitter made of alumina (Ceramic Foam) is installed at the middle. At both sides of the emitter, porous quartz glass plates with many pores are set up. A mixture of air and methane is introduced into the porous media, and flows uniformly across the cross section, where the flow direction changes regularly. Combustion occurs around the surface of the porous emitter. Through energy recirculation, the temperature of the emitter reaches about 1500K under the condition of the equivalence ratio of 0.2. Furthermore, the long-wavelength components of the radiation emitted from the porous emitter are partially absorbed by the porous quartz glass, then, the short wavelength components are introduced into the TPV cell. Though the view factor was very small and there was multiple-surface reflection by the quartz glass, we obtained the output power, which was small, using the super-adiabatic combustion TPV system.

The spectral emission of a ceramic plate coated with a rare-earth oxide thin film was investigated for thermophotovoltaic (TPV) applications using a one-dimensional radiative transfer analysis. The selective emitter has emission bands at wavelengths around 1 and 1.5 µm due to erbium. In the temperature range between 1400 and 1500 K, the radiant energy within these bands is remarkably large, because the Planck distribution has a peak at a wavelength of approximately 2 µm. In addition, the spectral response of a GaSb TPV cell has a peak at around 1.5 µm; therefore, the radiant energy of the emission bands is quite useful for the TPV generation of electricity. The total spectral efficiency for both the 1 µm and 1.5 µm bands reaches a maximum value of 0.295 for a film thickness between 0.2 and 0.3 mm.

Understanding and optimisation of heat transfer, and in particular radiative heat transfer in terms of spectral, angular and spatial radiation distributions is important to achieve high system efficiencies and high electrical power densities for thermophtovoltaics (TPV). This work reviews heat transfer models and uses the Discrete Ordinates method. Firstly onedimensional heat transfer in fused silica (quartz glass) shields was examined for the common arrangement, radiator-air-glass-air-PV cell. It has been concluded that an alternative arrangement radiator-glass-air-PV cell with increased thickness of fused silica should have advantages in terms of improved transmission of convertible radiation and enhanced suppression of nonconvertible radiation.
