Abstract
A crossed compound parabolic concentrator (CCPC) is a non-imaging concentrator which is a modified form of a circular 3D compound parabolic concentrator (CPC) obtained by orthogonal intersection of two 2D CPCs that have an optical efficiency in line with that of 3D CPC. The present work is about the design and fabrication of a new generation of solar concentrator: the hybrid photovoltaic (PV)/thermal absorptive/reflective CCPC module. The module has a 4× CCPC structure truncated to have a concentration of 3.6× with a half acceptance angle of 30°. Furthermore, an experimental rig was also fabricated to test the performance of the module and its feasibility in real applications such as building-integrated photovoltaic (BIPV). 3D printing and Computer Numerical Control (CNC) milling technologies were utilized to manufacture the absorber and reflective parts of the module.

A great concern that the world faces now is the rising global temperature and subsequent phenomena of global warming
Even though it is recognized that there are natural causes for climate change, it is widely accepted by scientists and climatologists that human activity is the number-one cause for the global warming
°C, with each increase in degree an average of cell with a base temperature of 25 C, with each increase in degree an average of 0.45% of efficiency isof depleted [15]. These studies show that the thermal management of PV operating temperature is a key factor in obtaining a reliable and efficient system. The relevance of such A/R crossed compound parabolic concentrator (CCPC) module is when it is applied to building-integrated photovoltaics (BIPV)
Summary
A great concern that the world faces now is the rising global temperature and subsequent phenomena of global warming. The limitations of 3D CPC with decreased geometrical concentration ratio due to shape shift from from circular to hexagonal entry aperture and the circular exit aperture can be solved by providing a circular to hexagonal entry aperture and the circular exit aperture can be solved by providing a square square entry and exit aperture area. CCPC, which is a modified form of circular 3D CPC, has square entry and exit aperture area. CCPC, which is a modified form of circular 3D CPC, has square entry entry and exit apertures. Apart from having optical efficiency in alignment to that of circular 3D CPC, square inlet and exit apertures help to increase the area of collected solar radiation when multiple the square inlet and exit apertures help to increase the area of collected solar radiation when multiple. CCPC is eliminated littletosacrifice to the geometric concentration ratio and optical efficiency [9].
