摘要

This study aims to examine the potential of Si/SiO2-based one-dimensional photonic crystals (1D-PhCs), which can be considered as advanced and alternative materials to traditional Si/SiO2 multilayer structures for thermophotovoltaic (TPV) applications. This work will particularly emphasize the improvement of the thermal stability and optical properties of the Si/SiO2-PhCs under high-temperature operating conditions. Using the transfer matrix method (TMM), the optical properties of the Si/SiO2-PhCs will be analyzed, and the reflective properties of the Si/SiO2-PhCs in the visible and infrared regions will be particularly emphasized. The results show that Si/SiO2-PhCs have better thermal stability and optical properties compared to conventional Si/SiO2 multilayer structures.
