“…The increased tolerance of the ADG Fresnel lens is beneficial as it reduces the sensitivity of the system to manufacturing, assembly or tracking errors, as well as the impact of temperature variations on lens performance. Zhuang et al [17] designed another form of a Fresnel lens for CPV systems. This lens can be seen as two assembled parts, the first with conventional prisms on the outer part and the second with TIR prisms on the inner part, as shown in Figure 9a.…”

Concentrator Photovoltaic (CPV) technology, by using efficient optical elements, small sizes and high efficiency multi-junction solar cells, can be seen as a bright energy source to produce more cost-effective electricity. The main and basic idea is to replace the use of expensive solar cells with less expensive optical elements made from different materials. This paper aims to give to the readers a rapid and concise overview of CPV and the main characteristics to be considered when designing a CPV system. It reviews the main optical configurations presented in the literature, their advantages and drawbacks, as well as the recent progress in the concentration ratio and the major performances achieved in the field. The paper considers the more recent works, their optical designs, as well as their optical and electrical performances. It also relates the major achievements on the industrial side with the major milestones in CPV developments.

“…where n is the refractive index, λ is the wavelength, and a 0 , a 1 , a 2 , a 3 , a 4 , a 5 , etc., are the constant coefficients. a 1 = −2.44753480 × 10 −4 , a 2 = 1.41557870 × 10 −2 , a 3 = −4.43297810 × 10 −4 , a 4 = 7.76642590 × 10 −5 , a 5 = −2.99363820 × 10 −6 , and the unit of λ is µm [35]. Different distributions of the Fresnel lens' slope error and the FFFSC's tracking error are proposed in literature which is based on the long-term performances of the solar system [36,37], but both of them are ignored in the simulation.…”

Most sun-tracking systems of solar concentrators are expensive, sensitive to operational costs, and complicated in optical design in which the receiver must be free to rotate about the axis. To overcome the aforementioned problems, this study presents a fixed-focus Fresnel lens solar concentrator (FFFSC) using polar-axis tracking which allows the Fresnel lens to concentrate sunlight to a fixed small heat-receiving area and the receiver remained fixed in location and rotation. Experimental research has been conducted to obtain the optical characteristics of the FFFSC for different solar times, tracking errors, and periodical adjustment errors. It has been found that maximum values of the relative optical efficiency loss (η re-opt,loss) and minimum value of the optical efficiency (η opt) of the FFFSC for different solar times are 1.87% and 71.61%, respectively. The mean value and maximum value of the local concentration ratio of the solar flux on the receiver are more than 86.64 and 1319.43, respectively. When the tracking error and periodical adjustment error are within 1 • , the η opt of the FFFSC can reach 70.38% and 68.94%, respectively. The optical characteristics of FFFSC is also verified numerically. Especially, according to the total year simulation of the FFFSC's optical characteristics, maximum value of η re-opt,loss is 0.116%, which means the proposed the FFFSC can achieve fixed-focus.

The concept of a high-concentration optical system is introduced detailing the various design types and focusing only on those aimed at photovoltaic (PV) applications. This will include point focus, line focus, imaging, nonimaging, and the classical cassegrain set-up. The theory of high-concentration optics is explained in terms of idealised concepts and maximum limits for each concentrator type and combination. The optical system is broken down into the different stages and materials possible in a high-concentration configuration. The physics of reflective and refractive optics are described, and their associated errors, advantages and a brief overview of past milestones, and recent research trends in the area of high-concentration PVs are presented. Current primary and secondary optics are geometrically explained covering Fresnel, parabolic, heliostat, compound parabolic, hyperboloid, v-trough, and dome-shaped optics. This chapter also covers examples of new secondary optics, such as the three-dimensional crossed-compound parabolic concentrator and the square elliptical hyperboloid concentrator. The aim of this chapter is to provide the basic optical behaviour of high-concentration designs aimed at PV applications considering their geometry, materials, and reliability.
