“…In the ideal 2D CPC design, the rays incident on the rim of the exit aperture are said to be at the boundaries of failure regions, which in 3D designs are realised for skew rays. A 3D CPC can be made from revolving the 2D profile (circular), by crossing two linear CPCs (square), or by more complex computation methods for specific geometries such as the rotationally asymmetrical compound parabolic concentrator [43].…”

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.

Summary The use of concentrating systems has been proposed as a way to reduce the cost of electrical energy from photovoltaic (PV) module. Since 1970s, different solar collector designs have been used to increase energy flux on the PV module. This study aims at providing a comprehensive review of development in the application of compound parabolic concentrators (CPCs) to solar photovoltaic conversion for the past five decades. By narrowing down the application of CPCs to electrical energy only gives a reader an opportunity to clearly understand the detail development stages, challenges, and research opportunities for further improvement. From this review, it has been found that during 1970s, all studies on the application of CPCs to solar photovoltaic conversion were mainly focused on establishing technical feasibility and cost effectiveness. Thereafter (1981‐May 2018), extensive studies were carried out to resolve challenges that were observed during the establishment stage. However, it has been found that even though the power output of the PV modules with the CPC was always higher than similar modules without the CPC, the values were less than the expected (theoretical) results. This was due to optical losses, series resistance losses, non‐uniform illumination effect, and high operating cell temperature effect. In addition, high cost of the PV‐CPC systems and low concentration ratio of the CPCs were also the main concerns of various researchers.

“…For a GCR of 4.91, simulation results showed an optical concentration ratio of 4.59 and experimentally showed 4.17. Abu‐Bakar et al designed a rotationally asymmetrical CPC for building integrated applications with GCR ranging from 1.73 to 6.59. The optical efficiency resulted from simulation ranges between 94% and 98%.…”

Summary Improving photovoltaic (PV) system power output is the main target of research in this field. Using concentrators with PV systems should increase the power output and consequently reduce the power production costs. However, using concentrators with PV (CPV) system has a drawback of a higher PV system temperature, which affects the voltage produced by the system leading to lower overall system power output. This paper experimentally investigates the performance of a polycrystalline silicon PV cell with a low‐concentration ratio square aperture concentrator. A 50 × 50 mm cell was tested without concentration and with a range of geometric concentration ratios (GCRs) of 4, 6, 8, and 10. Various cooling methods were studied, including no cooling, passive cooling by using finned heatsink, and active cooling by using finned heatsink and a fan, and the CPV performance was presented in conversion efficiency, the electrical power gain, and the reduction in PV material at various testing conditions. Significant improvement was obtained by using square aperture concentrator at different GCRs with highest power gain of 362.85%, PV cell material reduction of 78.39%, and efficiency increase by 72% at GCR 10 and active cooling. The results do not consider the power needed to extract the heat generated by the concentration and reduce the cell temperature by using air cooling. But the extracted heat enhances the CPV system output if it is harnessed in domestic applications such as water heating applications. These results highlight the potential of the developed CPV system.
