What is the process in design a Compound Elliptical Concentrator and Compound Parabolic Concentrator if I wanted to achieve 100% optimal concentration ? Let's assume random numbers of: A light source being 14 meters wide, the aperture is 4 meters wide and the distance between them being 12 meters.
I was doing random searches on solar energy and came across solar concentrators which I've never heard of before, but saw you can design them based on knowing information above. I can't find anything easy enough to understand so a newbie like me can follow clearly.
For example, for the CPC. The equation is for the maximum concentration: $$C=\frac{1}{sin^2(\theta)}$$
If I wanted a 100% concenctration would have a 1 (100%) in place of the C then solve for the theta to get the half acceptance angle ? Would I go backwards from this and adjust the base of the concetrator to have an aperture of 4 meters and a base of whatever gives me an angle of theta?
Here is an image of what I meant (found randomly online with no explanation):
