Summary
The rules for casting maximum energy on a cell placed in a static concentrator of minimum entry aperture are derived. A concentration of 9.13 for collecting the direct sunbeam throughout the year and of 4.5 for collecting diffuse light are upper bounds when using practical materials. Practical bifacial solar cells required to achieve those figures are presented. A prototype of concentrator with bifacial cells has been fabricated and its results are also presented. Based on the possible improvements of such a concentrator we arrived at a cost estimate of $3.19 W/peak.
