Claim 0:
1. A divergent Fresnel lens and non-imaging Compound Parabolic Concentrator (CPC) based non-tracking high concentration ratio solar concentrator system comprises a domed divergent Fresnel lens, and a non-imaging CPC concentrator with a upper opening or a non-imaging CPC concentrator with a domed transparent top cover, the domed divergent Fresnel lens is connected to the non-imaging CPC concentrator with its bottom edge, overlapping with the circumference of the upper opening of the non-imaging CPC concentrator, or the domed divergent Fresnel lens is attached onto the domed transparent cover of the non-imaging CPC concentrator;
Wherein, the domed divergent Fresnel lens diverges incident sunlight before it reach to upper aperture of the non-imaging CPC with a upper opening or the non-imaging CPC concentrator with a domed transparent top cover and reduces its incident angle relative to the axis of the CPC making it fall in acceptance half-angle of the non-imaging CPC with a upper opening or the non-imaging CPC concentrator with a domed transparent top cover any time during the diurnal day, so that sunlight incident to the upper aperture of the non-imaging CPC with a upper opening or the non-imaging CPC concentrator with a domed transparent top cover with any angle will be collected and concentrated by the CPC without tracking the sun.
