Patent number: 9027292Abstract: A passive collimating skylight system includes an energy-receiving aperture defining a first plane and an energy-delivering aperture defining a second plane that is spaced apart from and non-parallel to the first plane. An energy-directing passageway extends between the energy-receiving aperture and the energy-delivering aperture to redirect radiant energy incident on the energy-collecting aperture over a range of incidence angles to the energy-delivering aperture so that the redirected radiant energy emerges from the energy-delivering aperture over a range of emergence angles that is smaller than the range of incidence angles. The passageway is defined by a wall having a first end that defines the energy-delivering aperture and a second end that defines the energy-collecting aperture, the wall tapering inwardly and having a reflective inner surface along substantially the entire length from the first end to the second end.Type: GrantFiled: October 22, 2013Date of Patent: May 12, 2015Assignee: Entech Solar, Inc.Inventors: Mark J.

Patent number: 6031179Abstract: A color-mixing lens for use in a concentrator system and methods of manufacture and operation thereof. The color-mixing lens includes: (1) a light-transmissive substrate that receives broad spectrum light from a source, (2) a first plurality of prisms, located on the substrate, that refract and chromatically disperse the light received therein toward a first plurality of locations on an active region of a target cell, and (3) a second plurality of prisms located on the substrate that refract and chromatically disperse the light received therein toward a second plurality of locations on the active region. Relative dimensions of the first and second pluralities of prisms are preselected to cause the chromatically-dispersed light to mix and thereby increase a power output of the target cell by reducing inter-junction currents therein.Type: GrantFiled: May 9, 1997Date of Patent: February 29, 2000Assignee: Entech, Inc.Inventor: Mark J.

Patent number: 4719904Abstract: A solar thermal energy collector includes a thermal receiver for receiving thermal energy from incident solar radiation and converting that energy, with minimum heat loss, into thermal energy transferred to and carried by a thermal fluid in a copper conductor. The copper tube is placed within a lower aluminum extrusion and may be secured thereto with a metal-filled silicone adhesive. The adhesive also acts as a heat-transfer device. The lower aluminum extrusion rests upon a foundation of isocyanurate urethane insulation which in turn rests upon the lower portion of a solar collector so that the central axis of the thermal fluid conducting tube lies along the axis of concentration of received solar energy. An upper aluminum extrusion is placed on top of the upper half of the copper tube and secured thereto with metal-filled silicone adhesive. The top surface of the upper aluminum extrusion is painted black and has a triangular-faceted surface.Type: GrantFiled: July 22, 1986Date of Patent: January 19, 1988Assignee: Entech, Inc.Inventor: Mark J.

Patent number: 4711972Abstract: A solar energy collector including a primary optical concentrator, one or more solar cells and an improved solar cell cover design is provided. Each of the solar cells includes a flexible cell cover which significantly reduces optical losses due to gridline obscuration of active cell area and also due to reflection from the cover itself. The cover comprises an optically clear, flexible material, such as a silicone polymer, placed over the illuminated surface of each solar cell, with prisms formed on the outer surface of the cover such that incident sunlight is refracted by the prisms onto active cell area rather than partially onto non-active gridlines or conducting elements. Each of the prisms has a predetermined shape depending on the type of primary optical concentrator used in the solar energy collector.Type: GrantFiled: August 4, 1986Date of Patent: December 8, 1987Assignee: Entech, Inc.Inventor: Mark J.

Patent number: 4545366Abstract: A refractive optical concentrator for focussing solar energy on to small focal spots includes a linear Fresnel lens optically cross-coupled with simple cylindrical lenses. The cross-coupled lens concentrator comprises an optically clear dielectric material, such as acrylic plastic, with a plurality of linear prisms formed on its inner surface, and a plurality of perpendicularly mounted cylindrical lenses formed on its outer surface, such that the cylindrical lenses focus the sunlight toward a series of lateral axes and the prisms re-focus the sunlight along a longitudinal axis. The bi-focussed radiant energy is thereby concentrated upon a series of photovoltaic cells for transforming sunlight into electrical energy.Type: GrantFiled: September 24, 1984Date of Patent: October 8, 1985Assignee: Entech, Inc.Inventor: Mark J.

Patent number: 4154219Abstract: A prismatic plate is mounted with its flat face exposed to the sun on a reflector panel for use in a solar energy collection system. The plate includes a plurality of triangular prisms with parallel longitudinal axes shaped to provide total internal reflection of incident light rays. Each prism has a cross section forming a right-angled isosceles triangle with the two equal-length, rear faces of the prism oriented at 45 degrees relative to the front face of the plate. The base of each prism forms or is parallel to a front plate surface which receives incident solar light rays. The rays are transmitted through the plate cross section without refraction in the plane of the cross section to be reflected from the two rear faces and back out the front face toward a solar receiver. The prism material has an index of refraction equal to or greater than the square root of two so that there is total internal reflection from the prism faces.Type: GrantFiled: March 11, 1977Date of Patent: May 15, 1979Assignee: E-Systems, Inc.Inventors: Youdhishthir P.

Patent number: 4069812Abstract: A curved prismatic, Fresnel-type lens primarily used for concentrating sunlight in a solar energy collector. The lens comprises a substantially smooth, convex outer surface and a plurality of prisms arranged side-by-side along a curve on the inner surface to direct incoming light to a common area. Each of the individual prisms has a front and back face joined by a bottom face. The front and back faces of the prisms are oriented such that the angle of incidence of the incoming light with the front face is equal to the angle of incidence of the outgoing light with the back face. Further, each of the prisms is arranged along the curve such that they do not obstruct light passing through any adjacent prism. The bottom face of each prism is over-extended beyond the path of the light passing through the prism to prevent loss of light due to blockage by the bottom face or the rounded point between the back face and bottom face.Type: GrantFiled: December 20, 1976Date of Patent: January 24, 1978Assignee: E-Systems, Inc.Inventor: Mark J.

Patent number: 3991741Abstract: An array of linear lenses is used as a combination roof-skylight-solar collector. The lenses are oriented at a given latitude to face the most remote of the earth's poles inclined by the local latitude angle. Moving absorbers are used to receive the sunlight at the focal spot of each lens. The absorbers move back and forth during the day as the sun's position changes, causing the focal spots to move.Type: GrantFiled: March 20, 1975Date of Patent: November 16, 1976Inventors: Leonard L. Northrup, Jr., Mark J. O'Neill
