Abstract :
This paper describes a new method to design a static concentrator which is wide acceptance angle. The structures are the lightguide and a micro prism arrays to collect the sunlight from different incident angles. This innovative concentrator is 31% efficiency on normal incidence and 15° acceptance angle.
