摘      要：The near-field effect can be used to improve the output power of the near-field thermophotovoltaic device(NTPV).The nearfield radiative heat transfer in the near-field thermophotovoltaic device can be enhanced by the excitation of hyperbolic modes and the coupling of surface plasmon *** this study,we design a two-body near-field thermophotovoltaic system based on hyperbolic *** multilayer structure on the emitter is composed of Ga-doped ZnO(GZO)and hafnium dioxide(HfO2).The gratings are on the InAs photovoltaic *** electrodynamics and rigorous coupled-wave method are employed to calculate radiative heat *** is found that the NTPV system with multiple microstructures performs better than the NTPV system just with single *** NTPV system performs better in a wider vacuum *** output power and efficiency are enhanced by the GZO-HfO2surface plasmon polaritons in multilayer *** gratings can monitor the spectral heat flux to match the cell band gap to enhance the performance of the near-field thermophotovoltaic *** investigation provides a novel approach for improving the output power of a two-body near-field thermophotovoltaic system.
