The solar concentrator is designed in the form of a compound parabolic concentrator CPC of relatively light metal (aluminum) with a reflective inner surface (coated with a reflective material). Parabola is characterized by a high concentration of incident rays at one point (the focus) of a large radiation field, in other words the design has a relatively large acceptance angle and a small amount of diffusion compared to other concentrators. The CPC of circular cross section has been designed by using (Zemax) optical design program, with a different concentration ratio for each sample (C = 1, 2, 3, 4, 5). The design of the sample should be consistent with the shape of the detector (which is attached to the exit aperture). A plastic cover has been used to cover the entrance aperture to protect against external environmental factors (such as moisture, dust, and rain), made of hard material (PMMA) which has a good thermal expansion coefficient.
