[Abstract]:Solar thermal photovoltaic cell (STPV) system is another hot research object in the field of solar power utilization. Using high performance spectral control module will make it have high energy conversion efficiency. This paper will focus on the spectral control module of STPV system, design and analyze the performance optimization, and optimize the design of STPV battery system based on the spectral control module. The effect of area ratio coefficient and geometric concentration ratio on the performance of STPV system is analyzed. The specific research contents include the following aspects: adopting the theory of equivalent medium, the multilayer structure is reasonably designed. The strict coupled wave analysis (RCWAA) algorithm is used to scan and calculate the spectral characteristics of multilayer structures, and the diffuse characteristics are analyzed. The effects of the parameters such as the number of layers, the duty cycle of metals and the width of top and bottom layers on the spectral properties of multilayer structures are discussed. Based on the equivalent medium theory and transfer matrix theory, the diffuse properties of two-dimensional DSi-SiO2 photonic crystals are studied. The effects of doping concentration, structure height and filling ratio of photonic crystals on their spectral properties are discussed. The spectral properties of one-dimensional Si-SiO2 photonic crystals and one-dimensional Ag-MgF2 photonic crystals are studied by using transfer matrix theory. Their diffuse properties are analyzed, and the effect of the number of cells of two kinds of photonic crystal structures on their spectral characteristic curves is discussed. The effective transmittance coefficient and transmission efficiency of the modified structure are also analyzed by modifying the two kinds of photonic crystals. By comparing and analyzing the effective transmission coefficient and transmission efficiency of the modified structure, the superiority of the semi-thick film photonic crystal structure is verified. The energy equation of the solar thermal photovoltaic cell system is established. The effects of the upper limit of the truncated wavelength of ideal absorption spectrum and the lower limit of truncated wavelength of ideal emission spectrum on the absorber-radiator temperature, absorber efficiency, battery efficiency and total system efficiency are analyzed. The optimal truncated wavelength upper limit of ideal absorption spectrum and the lower limit of truncated wavelength of ideal emission spectrum are determined, which provides a reference for the structure design of spectral control module in chapters 2 and 3. The absorber and radiator based on multilayer structure are adopted. One-dimensional Ag-SiO2 photonic crystal is used as photonic filter and in GaAs SB as photovoltaic cell. Under the condition of unit area ratio coefficient and optimum area ratio coefficient, the radiator / absorber temperature and absorber efficiency are calculated and compared. The differences among radiator photon filter efficiency, cell efficiency and solar thermal photovoltaic cell system efficiency are discussed. The system output power curves corresponding to different geometric condensing ratios are given, and the advantages of high output power are verified.
