摘要： One or more thin film solar cells in which the intrinsic layer of substantially amorphous semiconductor alloy material thereof includes at least a first band gap portion and a narrower band gap portion. The band gap of the intrinsic layer is spatially graded through a portion of the bulk thickness, said graded portion including a region removed from the intrinsic layer-dopant layer interfaces. The band gap of the intrinsic layer is always less than the band gap of the doped layers. The gradation of the intrinsic layer is effected such that the open circuit voltage and/or the fill factor of the one or plural solar cell structure is enhanced.

摘要： A method for the low temperature fabrication of doped polycrystalline semiconductor alloy material. The method includes the steps of exposing a body of semiconductor alloy material to a reaction gas containing at least a source of the dopant element, and establishing an electrical potential sufficient to sputter etch the surface of said layer, while decomposing the reaction gas. This allows for the deposition of a layer of doped amorphous semiconductor alloy material upon the body of semiconductor alloy material. Thereafter, the doped layer of amorphous semiconductor alloy material is exposed to an annealing environment sufficient to at least partially crystallize said amorphous material, and activate the dopant element.

摘要： A support system for retaining a photovoltaic device on a generally planar surface, without any mechanical connection to the surface, includes a frame assembly which rests upon the surface and supports one or more photovoltaic devices in a spaced apart relationship with the surface. At least one ballast pan is attached to the frame assembly. The ballast pan is configured to retain a ballast material therein. The ballast pan may comprise a peripheral ballast pan which extends along the perimeter of the assembly or it may comprise an internal ballast pan which is disposed beneath the photovoltaic device. Also disclosed herein is a method for using the support system.
