Abstract

In order to achieve competitive system costs in mass-production, it is essential that CPV concentrators incorporate sufficient manufacturing tolerances. This paper presents an advanced concentrator optic comprising a Fresnel lens and a refractive secondary element, both with broken rotational symmetry, an optic producing both the desired light concentration with high tolerance (high acceptance angle) as well as an excellent light homogenization by Köhler integration. This concentrator compares well with conventional Fresnel-based CPV concentrators.

  14. The same BK7 glass has been considered for all the SOE’s under comparison. Though BK7 can be molded (see for instance, http://www.rpoptics.com/index.php?page=rpo-moldable-glass-data ) is more common the use of, for instance, B270. The light absorption in B270 is slightly higher than in BK7, which causes that if the comparison is done using B270, the efficient of the RTP (whose optical path is longer) is penalized the most.

The design with highest CAP* in this reference has a rotationally-symmetric CPC-type TIR-based secondary. It achieved CAP* = 0.54 for a square aperture and square cell (for which the FK has a higher value of CAP* = 0.57–0.61). Moreover, it produces a poor irradiance uniformity. It also has the encapsulation problems discussed in Section 5.
