THERMOPHOTOVOLTAIC DEVICE WITH SELECTIVE EMITTER

摘要

A thermophotovoltaic device having a selective emitter includes thermophotovoltaic cells adapted to receive energy from an energy source. A dual wall barrier which defines a space is disposed between the thermophotovoltaic cells and the energy source. Atmosphere is vacated from the space to create a vacuum or the space is filled with inert gas to provide a non-oxidizing environment. A selective emitter is disposed in the space within the non-oxidizing environment.
