The primary concentrator polymeric shell and secondary concentrator polymeric shell are coupled together to retain a common the liquid. The multifunction photovoltaic cell is dimensioned having a receiving side area of that small value effective to maintain a working temperature within the liquid between 100-125degreesC. At least a portion of the non-imagining secondary concentrator polymeric shell is configured with a logarithmic profile symmetrically disposed about the cell axis. The secondary concentrator comprises a logarithmic concentrator having a the liquid retaining polymeric shell configured with a logarithmic profile extending from the receiving portion to an exit aperture, and a compound parabolic concentrator extending from the exit aperture to a tip. The liquid retaining polymeric shell is configured with a profile effective to present the homogenized light at an exit plane. The receiving side of the multifunction photovoltaic cell is located at the exit plane. The liquid retaining polymeric shell of the compound parabolic concentrator is integrally formed with the liquid retaining polymeric shell of the logarithmic concentrator. The liquid retaining polymeric shell of the primary concentrator is coupled in liquid retaining relationship with the liquid retaining polymeric shell of the logarithmic concentrator. A flat back support extensible along ground surface is configured to support the array of solar radiation responsive cells in stationary fashion. It further comprises an electrically insulative support lattice having an array of support surfaces configured to receive and locate a photovoltaic cell for the interaction with the homogenized radiation, and configured for supporting the array network. The back support further comprises a frame (62) of rectangular configuration supporting the support lattice. Each primary concentrator is configured with an outwardly disposed polymeric sheet component having a convex lens external profile and an inwardly disposed generally concave polymeric sheet component sealably fixed to the underside of the outwardly disposed polymeric sheet component to provide a cavity retaining the liquid to define a concavo-convex shaped imaging lens. It comprises an assemblage of correction lenses effective to provide correction for chromatic aberration at the image plane. Each correction lens is configured with a first polymeric sheet component having a convex lens profile and a second polymeric sheet component sealably fixed to one side of the first polymeric sheet component to provide a cavity retaining the liquid to define a correction lens. The secondary concentrator is configured as a molded discrete polymeric sheet component at least a portion having a logarithmic profile and defining a homogenization cavity retaining the liquid. The secondary concentrator logarithmic profile extends from the receiving portion to an exit and further comprises an integrally formed compound parabolic concentrator extending from the exit. The discrete polymeric sheet component extends from the exit to a tip. It is configured with a parabolic profile effective to focus the homogenized light at an exit plain located adjacent the tip and defining a cavity retaining the liquid in common with the cavity of logarithmic profile. The primary concentrator imaging lens is of hemispherical shape disposed about a cell axis and extending to an imaging lens exit area. The secondary concentrator is symmetrically disposed about the cell axis and comprises a logarithmic concentrator having an entrance configured and located for receiving radiation at the image plane and having surfaces extending from the entrance logarithmically approaching the cell axis to an exit; and a compound parabolic concentrator having surfaces located for receiving radiation from the logarithmic concentrator exit and concentrating it at the photovoltaic cell receiving side. The secondary concentrator further comprises a conical concentrator having an entrance adjacent the imaging lens exit area and an exit adjacent the image plane and having side surface(s) inclined toward the cell axis. The primary and secondary concentrators are configured to retain a common the liquid. The system comprises array(s) of panels supported over a ground surface between oppositely disposed panel arrays ends. Each panel has an array of solar radiation responsive cells. Preferred Property: The polymeric shells exhibit a thickness of 150-200 microns. The solar radiation cell exhibits a height of about 2 and 3/4 inches.
