Thermophotovoltaic device

摘要

A thermophotovoltaic device ( 10 ) includes an energy source ( 12 ) compatible with thermophotovoltaic cells and thermophotovoltaic cells ( 14 ). A filter ( 16 ), adapted to filter out long wavelength energy, is positioned between the energy source ( 12 ) and the thermophotovoltaic cells ( 14 ). The filter ( 16 ) has dual walls ( 30 & 32 ) with a low conductivity space ( 34 ) between the walls ( 30 & 32 ) which is adapted to break the convection heat transfer path from the energy source ( 12 ) to the thermophotovoltaic cells ( 14 ).
