摘要

In this paper, we proposed a new configuration of concentrator in solar PV system. A special optical system in the concentrator used in focusing sun light to solar cell is proposed, the system compose of an aspherical surface and a specific diffusing surface. The uniform-squared light pattern is obtained on the solar cell, the shape and size of light pattern can be modulated by the parameters of the diffusing surface. In order to decrease the weight of the lens, the concentrator in Fresnel lens type is built at last. Besides, the optical efficiencies formed by the aspherical concentrator and Fresnel concentrator are about 92% and 77%, the concentrations are about 720mW/mm~2 and 640mW/mm~2, and the acceptance angles are about 0.35° and 0.30°, respectively. The tolerances in assembling the component of the concentrator are also discussed in detail.
