    Abstract: The present disclosure provides systems and methods for depositing an alkaline metal layer on an absorber to generate a copper-poor region at a surface of the absorber. The copper-poor region provides an increased efficiency over non-treated absorbers having copper-rich surfaces. The alkaline metal layer may be deposited by any suitable deposition method, such as, for example, a wet deposition method. After the alkaline metal layer is deposited, the absorber is annealed, causing the alkaline metal layer to interact with the absorber to reduce the copper-profile of the absorber at the interface between the alkaline metal layer and the absorber.

    Abstract: A method for fabricating a solar cell using a nozzle assembly that includes a base portion, a scriber coupled to the base portion, and a nozzle coupled to the base portion such that the nozzle is positioned a predefined distance from a tip of the scriber is provided. The method generally comprises positioning a substructure that includes a buffer layer and an absorber layer proximate to the base portion. A P2 line is scribed through the buffer and absorber layers of the substructure using the scriber tip. A nanoparticle solution is sprayed, using the nozzle, onto at least one portion of the buffer layer at a predefined pressure when the P2 line is being scribed through the buffer and absorber layers such that a transparent conductive oxide (TCO) layer is inhibited from forming over the portion of the buffer layer that is being sprayed with the nanoparticle solution.

    Abstract: Methods and systems for repairing oxidation of CIGS surfaces during manufacture of a CIGS solar cell are generally disclosed. Oxidation of an absorber reduces the photoluminescence intensity of the CIGS surface. The absorber is immersed in a reduction tank having a reducing reagent therein. The reducing reagent reverses the oxidation of the CIGS absorber, increasing the interface quality and corresponding photoluminescence intensity. After reversing the oxidation, a buffer layer is deposited on the CIGS absorber to prevent further surface oxidation.

    Abstract: A solar cell includes an absorber layer formed of a CIGAS, copper, indium, gallium, aluminum, and selenium. A method for forming the absorber layer provides for using an indium-aluminum target and depositing an aluminum-indium film as a metal precursor layer using sputter deposition. Additional metal precursor layers such as a CuGa layer are also provided and a thermal processing operation causes the selenization of the metal precursor layers. The thermal processing operation/selenization operation converts the metal precursor layers to an absorber layer. In some embodiments, the absorber layer includes a double graded chalcopyrite-based bandgap.
