英文摘要: For solar absorption characteristics of the microstructured surfaces, the composite microstructured surfaces are proposed based on the radiation characteristics of the single micro-structured surfaces. The relationship between the solar radiation photon and the composite microstructured surfaces is investigated. The effect of structure parameters and material properties on the absorption is analyzed. The coupling mechanism of the solar radiation photon and the composite microstructured surfaces is revealed. The theory model of the solar radiation photons along the composite microstructured surfaces is found. The absorption of the composite microstructured surfaces is elucidated under wide angles and different polarization modes. The internal mechanism of the absorption characteristics and the different polarization modes is clarified. The method of omnidirectional and polarization insensitive solar absorption is established. Furthermore, the morphology and absorption characteristics of the composite microstructured surfaces are illustrated under the alternation of experiment condition and process parameters. The project has a significant science value for the efficient utilization of the solar energy, and lays the theory basis for the investigation of structured surfaces of high efficient absorption.
