Principles of solar concentrators of a novel design
TL;DR: The ideal cylindrical light collector (OCL) as mentioned in this paper is a non-imaging collector with an effective relative aperture (f-number) = 0·5, which has a larger acceptance for diffuse light than concentrating collectors using imaging optics.
