By tuning the photon transport, wavelength- or directional-selective emitters/absorbers have been designed and applied to thermal photovoltaics, 28,29 28. The inside surface temperature of the steel is 800 K and the outside surface temperature of the insulation board is 350 K. The thermal conductivity of the stainless steel is 19 W/(m K) and the thermal conductivity of the insulation board is 0.7 W/(m K). The conductive heat transport through the layered wall can be calculated as Boltzman Transport Equation.
