Abstract
A detailed optical analysis of an inverted absorber compound parabolic concentrator, which separates the dissimilar effects of beam and diffuse insolation, gives the effect on the optical efficiency of varying the tertiary cavity height, the reflectance and the acceptance. For the system considered, the optical efficiency decreases with increasing tertiary cavity height and is higher for beam than for diffuse insolation. A high mirror reflectance is essential for an adequate optical performance.
