Design,Manufacture And Experiment Of Metamaterial Emitter Matching To GaSb TPV Cell

Thermophotovoltaic power generation technology is a technology that converts the radiant energy generated by a heat source into electrical energy through the photoelectric effect of a thermal photovoltaic cell.The technology has high energy output density,theoretical efficiency,and a wide range of energy sources that can be applied to many combustion scenarios.In addition,it can be coupled with traditional Stirling machines and Rankine cycles for cogeneration,which has high practical and application value.First,this paper designs and builds a thermal photovoltaic system,which includes a gas supply system,a burner,a radiator,a thermal photovoltaic cell,a heat dissipation system,and a data collection system.The performance test of the heat dissipation system was carried out,and it was found that the current heat dissipation system can effectively reduce the temperature of the radiator.Next,the oxide radiator is studied in this paper.A 5% nickel oxide-containing magnesium oxide radiator was prepared by granulation,molding,and sintering,and the radiation characteristics of the radiator were measured,and compared with the radiation characteristics in other literatures.Thirdly,this paper studies the effects of different types of radiators,gas flow,equivalence ratio and battery distance on thermal photovoltaic systems.The experimental results show that with the increase of gas flow rate,the temperature of flame,stainless steel tube,porous silicon carbide,magnesium oxide and metamaterial radiator are improved to different degrees.
