Abstract: A combustor applied in thermophotovoltaic system comprises a combustion device and a reversed tube covering the combustion device. The combustion device includes a combustion body made of a transparent and temperature resistant material and a burning unit disposed in the combustion body. When a burning-supported medium is adopted during burning via the burning unit, the radiant intensity is increased. The reversed tube then further redirects the hot product gas for reheating an outer wall of the combustion body in combustion. Therefore, uniform illumination is accordingly resulted for enhancing the radiant intensity. Accordingly, a photovoltaic cell plate connected to the combustor preferably transforms light into electricity. The present invention fully utilizes a micro system as well as miniature energy to offer advanced electricity.
