A two-dimensional triangular lattice photonic crystal heterostructure is designed for solar reflector.The reflectivity of the incident electromagnetic wave in the visible to near infrared wavelength range is simulated by the transfer matrix method and the variation of reflectivity with different incident angle is studied.The results shows that the structure displays perfect reflection for the near-infrared incident light at normal incidence.As the deflection angle increases,it shows high reflectance in visible-near infrared wavelength range.The structure should enable new application for omnidirectional total reflector for the visible to near infrared light.
