“…Therefore for the rays to exit it, aperture must be within the designed acceptance angle of the concentrator. The study on two-stage photovoltaic concentrators with Fresnel lenses as primaries and dielectric totally internally reflecting non-imaging concentrators as secondaries revealed that, higher concentration and more uniform flux distribution on the photovoltaic cell was observed in two-stage concentrator than the point focusing Fresnel lens [51]. Lateral view of a DTIRC [50] VII.…”

“…Figure 6. Side view for basic design of a DTIRC [31] DTIRC as a secondary concentrator has been widely used in various applications such as the pumping of power laser systems [32], concentrated photovoltaic (CPV) [14], and solar thermal application in space [33], [34]. Recently, Cruz-Silva et al [16] reformulate the Ning's formulation of DTIRC [31] to obtain an analytical framework for feasible designs which are easily implemented for computer numerical control (CNC) manufacturing and presented solar flux distribution in Linear Fresnel reflector (LFR) and parabolic through collector (PTC) using DTRIC as secondary concentrator.…”

“…This technology offers more open-ended structure for the systems, for example, upward-facing receiver [12] or appropriate heat storage design [13]. Besides, it provides higher concentration ratios [14]- [16] and effective power distribution [12]. The aim of this paper was to review secondary concentrators based on solar concentration and their other characteristics such as advantages, disadvantages, and performance.…”

Concentrating solar power (CSP) is a solar thermal technology that generates electricity from thermal energy through the sun.The electricitycan be generated with four different types of CSP technologies that include Parabolic Dish (PD) systems. In order to make this technology more practical, the efficiency of the solar technology should be improved.Solar concentration is one of the main aspects that can affect the system'sefficiency. This paper reviewed solar secondary concentrators and discussed their designs and performance. Besides, their strengths and weaknesses were compared. Generally, thesecondary concentrators couldincrease the solar concentration of the solar technologyup to 93 percent.

“…When a set of rays hits the front curved surface at the acceptance angle, it is refracted and directed to the exit aperture. Ning et al [82] discussed two-stage photovoltaic concentrators with Fresnel lenses as primaries and dielectric totally internally reflecting nonimaging concentrators as secondaries. The results indicated that two-stage concentrator suggests higher concentration and more uniform flux distribution on the photovoltaic cell than the point focusing Fresnel lens alone.…”

Throughout the recent centuries, the limits of using energy resources due to the cost and environmental issues became one of the scientists’ concerns. Because of the huge amount of energy received by the Earth from the sun, the application of photovoltaic solar cells has become popular in the world. The photovoltaic (PV) efficiency can be increased by several factors; concentrating photovoltaic (CPV) system is one of the important tools for efficiency improvement and enables for a reduction in the cell area requirement. The limits of the PV area can reduce the amount of absorbing irradiation; CPV systems can concentrate a large amount of sunlight into a smaller one by applying lenses or curved and flat mirrors. However, the additional costs on concentrating optics and cooling systems made CPV less common than nonconcentrated photovoltaic. This paper reviews the different types of PV concentrators, their performance with advantages and disadvantages, concentration ratio, acceptance angle, brief comparison between their efficiencies, and appropriate cooling system.
