    In this paper, we propose a novel technique to design flat Fresnel lens to achieve big concentration ratio, high uniform irradiance distribution while keeping F-number small using both refraction and total internal reflection (TIR) phenomena. Also, this method can be used to design concentrated photovoltaic (CPV) system without secondary optics lens (SOE). Design of a nonimaging Fresnel lens for solar concentrators () R. Leutz, A. Suzuki, A. Akisawa, T. Kashiwagi; Solar Ene 6, Abstract: An optimum convex shaped nonimaging Fresnel lens is designed following the edge ray principle. The lens is evaluated by tracing rays and calculating a projective optical concentration ratio.

    The ability to fabricate 4-level diffractive structures with 1 µm critical dimensions has been demonstrated for the creation of fast (∼f/ at nm) Fresnel zone lenses (FZLs) with >60% diffraction efficiency into the −1 focusing order and nearly complete suppression of 0 and +1 orders. This is done using tooling capable of producing optics with  mm apertures. The Fresnel lens used in non-imaging optical system was usually called non-imaging Fresnel lens. In this research, the Fresnel lenses were refracting optical elements but diffracting ones. According to the method of Ralf Leutz and Akio Suzuki [2], using minimum deviation and minimum dispersion to design a non-imaging Fresnel lens, which obeys Cited by: 6.

    Special applications of nonimaging optics such as Fresnel lenses for solar concentration [6] or solar concentration in general [7] have also been published, although this last reference by O'Gallagher describes mostly the work developed some decades ago. Other publications include book chapters. Fresnel lenses and accurate tracking has to be employed to keep the focus of the lens in place on the receiver/absorber. Fig. 2 illustrates the main technique used in the development of imaging Fresnel lens solar concentration systems. As seen, after the invention of Fresnel lens made of .

Shaped nonimaging Fresnel lenses have been designed according to the edge-ray principle, incorporating any combination of two acceptance half-angle pairs.

A numerical solution yields nonimaging lenses consisting of minimum-deviation prisms. If the outer surface of the lens must be smooth, the lens shape will be convex. In the last two decades, two classes of Fresnel lenses for use in solar collectors have been proposed. O’Neill () designed a point-focusing (not nonimaging) shaped Fresnel lens with high concentration, operating for normal incidence, making tracking inevitable.

Kritchman et al., a, Kritchman et al., b designed nonimaging Fresnel lenses according to the edge ray by: Fresnel lens is found to simplify the system structure and enhance the performance of photovoltaic systems. The flat and arched shape Fresnel lens surfaces are designed, respectively, based on 2D.

An optimum convex shaped nonimaging Fresnel lens is designed following the edge ray principle. The lens is evaluated by tracing rays and calculating a projective optical concentration ratio.

During the design of nonimaging Fresnel lenses, the reflectance losses at the refracting surfaces should be taken into account because, depending on the parameters of each prism, semiacceptance angle and output angle, these losses can decrease the total efficiency of the lens.
