Abstract

See full text

A solar concentrator photovoltaic (CPV) device in which concentrator elements (optics, PV cells and wiring) are laminated to form a composite, substantially planar structure. The concentrator optics are implemented by a solid (e.g. glass) optical element that defines a focal point at which solar light received by the optical element is concentrated. Using vacuum lamination techniques, a printed circuit structure attached by way of an adhesive layer onto a surface of the optical element. The printed circuit structure includes one or more non-conductive layers and conductors that are disposed on the non-conductive layers. The PV cell is connected to printed circuit structure, and is positioned at the focal point of the optical element. Optional front and/or back protective layers are also attached prior to the lamination process. A CPV array includes multiple devices formed on an optical tile using a string-like flexible printed circuit structure.
