Design Optimisation of Compound Parabolic Concentrator (CPC) for Improved Performance

A compound parabolic concentrator (CPC) is a well 
known non-imaging concentrator that will concentrate the solar 
radiation onto receiver (PV cell). This is also will lead to the 
decreases of concentration ratio but it will be negligible. In this 
paper, the flux distribution of untruncated and truncated 2-D hollow 
compound parabolic trough concentrator (hCPTC) design is 
presented. The untruncated design has initial height, H=193.4mm 
with concentration ratio, C_(2-D)=4. This paper presents the optical 
simulation of compound parabolic trough concentrator using raytracing 
software TracePro. Results showed that, after the truncation, 
the height of CPC reduced 45% from initial height with the 
geometrical concentration ratio only decrease 10%. Thus, the cost of 
reflector and material dielectric usage can be saved especially at 
manufacturing site
