Abstract
An article of manufacture includes a first and second PV cell layer, where the first and second PV cell layers are at least partially displaced from each other and define a continuous optical coverage area throughout a solar active area. The article provides for enhanced utilization of the active solar area.
Claims15
An article of manufacture, comprising:
- a transparent front sheet defining a solar active area, the front sheet structurally coupled to a back sheet, the front sheet and back sheet having a photo-voltaic (PV) device positioned there between, the PV device comprising:
- a first PV cell layer comprising a first photovoltaically active material;
- a second PV cell layer comprising a second photovoltaically active material;
- and
- wherein the first PV cell layer and the second PV cell layer are at least partially displaced and define a continuous optical coverage area throughout the solar active area and are electrically isolated from each other in the solar active area.

A method, comprising:
- forming a photovoltaic device, wherein the forming comprises providing a first photo-voltaic (PV) cell layer comprising a first photovoltaically active material and a second PV cell layer comprising a second photovoltaically active material, and positioning the second PV cell layer at least partially displaced from the first PV cell layer;
- interpreting an external circuit description;
- electrically coupling the first PV cell layer and the second PV cell layer in an electrical configuration selected in response to the external circuit description;
- providing a transparent front sheet and a back sheet;
- positioning the photovoltaic device between the front sheet and the back sheet, such that the front sheet defines a solar active area and the first PV cell layer and the second PV cell layer define a continuous optical coverage area throughout the solar active area and the first PV cell layer and the second PV cell layer are electrically isolated from each other in the solar active area;
- and
- structurally coupling the front sheet to the back sheet.
