The solar thermophotovoltaic system transforms the radiation emitted by thermal emitter into electrical energy when the emitter is heated by sunlights. The filter in the system reflects the longer wavelengths, and is transparent for the shorter ones. The optical filter can improve the efficiency of the solar thermophotovoltaic system. An 1-dimensional photonic crystal was studied numerically. It is shown that the cutoff wavelength of the filter is 2μm, and the average transmission for shorter wavelengths is > 70%, and the reflectance for longer wavelengths is > 90%. The 1-dimensional photonic crystal filter can improve the efficiency of the solar thermophotovoltaic system.
