The topical subject in the present model is to create model of surface texture from anisotropic single crystal silicon and evaluate reflection effect, including loss reflectance and photonics reabsorptivity . We also evaluated angle-dependent reflection effect. This three-dimension model describe pyramids distribute on the surface texture. We create the model that stand on the geometry property of pyramid. We calculate the reflectivity, shadow occupancy fraction, illuminate occupancy fraction, twice reflection occupancy fraction and loss reflectance for the quantitative evaluation of optic. This quantitative evaluation made use of vector as light motion. By comparing experimental and theoretical values, the reliability of a simulation technique was evaluated. We discover from result that antireflection and reabsorption effect better, when pyramid large and distribute densely. In the angle-dependent reflection, the reflectivity and illuminate occupancy fraction will increase, when illumination angle increase. The reabsorptivity is best to reach 75%, when illumination angle reach 90°.
