Abstract
A design method of a multi-zone grouped and light-homogenized Fresnel lens for a concentrating system includes: step 1, designing, according to a basic principle of a Fresnel lens, a planar Fresnel lens; step 2, establishing, according to an optical path characteristic of the concentrating system, an optical path equation of the concentrating system; step 3, determining a differential form of uniform distribution of luminous energy density; and step 4, based on the step 3, calculating design parameters of the multi-zone grouped and light-homogenized Fresnel lens to obtain the multi-zone grouped and light homogenized Fresnel lens. The obtained Fresnel lens can realize low-power concentrating, solve the problem that luminous energy is too concentrated under a high-power light-concentrating ratio, achieve high-uniformity design under different light-concentrating ratios, and improve the light-homogenized performance of the concentrating system, thereby solving non-uniform luminous energy density distribution on a surface of a photovoltaic cell.
