Beam integration for concentrating solar collector

摘要: A concentrating solar collector that utilizes a optical system to concentrate light onto PV cell (image plane), wherein the includes an array of first elements divide into separate beams, and secondary integrates (superimposes) beams in defocused state at image plane, thereby forming uniform distribution pattern on cell. The is positioned distance from aperture whereby rays each beam leaving element are parallel. plane (PV cell) located back focal point second element, all superimposed state. Optional intervening third used increase acceptance angle.
