Patent number: 9923112Abstract: A solar cell receiver for use in a concentrating solar system which concentrates the solar energy onto a solar cell for converting solar energy to electricity. The solar cell receiver may include a solar cell mounted on a support and with one or more III-V compound semiconductor layers. An optical element may be positioned over the solar cell and have an optical channel with an inlet that faces away from the solar cell and an outlet that faces towards the solar cell. A frame may be positioned over the support and extend around the solar cell with the frame having an inner side that extends above the support and faces towards the optical element. An encapsulant may be positioned over the support and contained between the optical element and the frame. The encapsulant may have enlarged heights at contact points with the optical element and the frame and a reduced height between the contact points away from the optical element and the frame. The solar cell receiver may be used in a solar cell module.Type: GrantFiled: June 24, 2014Date of Patent: March 20, 2018Assignee: SUNCORE PHOTOVOLTAICS, INC.Inventors: Lei Yang, Sunil Vaid, Mikhail Kats, Gary Hering, Philip Blumenfeld, Damien Buie, John Nagyvary, James Foresi, Peter Allen Zawadzki

Patent number: 8536504Abstract: The terrestrial solar tracking photovoltaic array includes a longitudinal support that may be constructed of discrete sections. The overall length of the array may be adjusted depending upon the necessary size of the array. A drive may be configured to rotate the longitudinal support in first and second directions about a first axis. Solar cell modules are positioned along the longitudinal support and may each include a rectangular case with a plurality of lenses that are positioned over corresponding receivers. Linkages may be connected to the solar cell modules and are axially movable along the longitudinal support to rotate the solar cell modules within second planes that each orthogonal to the first plane to further track the sun during the course of the day. The array may be configured to facilitate rotation about the first axis. The array may be constructed with a center of gravity of the array to extending through the longitudinal support.Type: GrantFiled: January 31, 2012Date of Patent: September 17, 2013Assignee: Suncore Photovoltaics, Inc.Inventors: Mikhail Kats, Gary D.
