    Abstract: A photovoltaic device 100 is provided comprising an absorber layer 416, wherein the absorber layer comprises a plurality of grains separated by grain boundaries. At least one layer is disposed over the absorber layer. The absorber layer 416 comprises grain boundaries that are substantially perpendicular to the at least one layer disposed over the absorber layer. The plurality of grains 412 has a median grain diameter of less than 1 micrometer. Further, the grains are either p-type or n-type. The grain boundaries comprise an active dopant. The active dopant concentration in the grain boundaries is higher than the effective dopant concentration in the grains. The grains 412 and grain boundaries may be of the same type or opposite type. Further, when the grain boundaries are n-type the bottom of the grain boundaries may be p-type. A method of making the absorber layer 416 is also disclosed.

    Abstract: Ein Aspekt der vorliegenden Erfindung stellt ein Verfahren zum Herstellen eines Filmes bereit. Das Verfahren schließt das Bereitstellen eines ein Sulfid umfassenden Targets in einer sauerstofffreien Umgebung, das Anwenden einer Vielzahl von Gleichstromimpulsen auf das Target zum Erzeugen eines impulsförmigen Gleichstromplasmas, das Zerstäuben des Sulfidtargets mit dem impulsförmigen DC-Plasma zum Auswerfen eines Schwefel umfassenden Materials in das Plasma und das Abscheiden eines das ausgeworfene Material umfassenden Films auf einem Träger ein. Ein anderer Aspekt der vorliegenden Erfindung umfasst ein Verfahren zum Herstellen einer photovoltaischen Vorrichtung.

    Abstract: A bearing assembly mounted in an x-ray tube includes a bearing race and a plurality of bearing balls positioned adjacent to the bearing race. The plurality of bearing balls are positioned within a bearing cage. The bearing cage is configured to evenly space the bearing balls within the bearing cage and prevent contact between adjacent bearing balls, thereby eliminating the problems of skidding wear and dynamic impact load between adjacent bearing balls in the bearing assembly.
