Abstract


Thermal photovoltaic cell system as an emerging green clean energy technologies , relative to the solar photovoltaic battery system with high system efficiency and output energy density , so more and more attention has been paid . Coupled with the rapid development of modern micro-nano manufacturing technology , I believe that in the near future , the thermal photovoltaic cell system will replace the traditional chemical batteries and solar cells , widely used in various industries and fields . Mathematical abstraction from the overall thermal photovoltaic battery system to establish a mathematical model for solving the performance , mainly hot for the design of high - efficiency photovoltaic battery system to do a more detailed analysis . First of all , from the basic heat radiation and heat transfer theory , the combination of near-field heat transfer theory , the establishment of a a thermal photovoltaic cell system contains complete near field solving model for analysis and design of high efficiency thermal photovoltaic cell system has laid a theoretical on the basis of . Second, it analyzes a thermal photovoltaic battery performance of the system with the spectral filter . Starting from the quarter of the modified membrane using heap spectral filter , to later take advantage of the improved genetic algorithm to optimize the the multilayers spectral filter , the audience high efficiency thermal photovoltaic battery system . Again, the analysis of the thermal photovoltaic performance of the battery system with the MIM ( Meta - Insulator - Metal ) type narrowband infrared emitting light source . With the FDTD simulation method , discussed in detail the MIM type narrowband infrared thermal emission of the light emission characteristics of the light source including the emission rate of the emission spectrum at a wavelength of the center wavelength and the center and MIM type structure of the material parameters and the geometric parameters of the relationship . Finally, the analysis of one with perfect reflector ideal thermal photovoltaic systems . Discuss this ideal limit of far-field and near-field performance when the vacuum gap is zero . In the near field , this ideal thermal photovoltaic cell system can simultaneously achieve a high system efficiency and high output power density . Further, some of the conclusions obtained for optimizing the performance of the system of thermal photovoltaic cell , such as a transmission source material selection and optimum vacuum gap , having a very useful guidance significance .
