  • Publication number: 20160372613
    Abstract: Embodiments of the invention related to a method for manufacturing a thin film solar cell backside contact. Prior to application of materials, a planar substrate is provided and an associated backside of the substrate is modified to form one or more pedestals. The modified substrate is layered with multiple layers of material, including a conducting layer, a reflective layer, and a passivation layer. The layered backside substrate is polished to expose portions of the conducting layer at discrete locations on the backside of the substrate. The exposed portions of the conducting layer maintain direct electrical communication between an absorber layer deposited on the layered backside substrate and the conducting layer.

  • Publication number: 20160326631
    Abstract: Embodiments relate to a sputter chamber comprising both a target surface and an anode surface. The sputter chamber has both an ingress and an egress to allow passage of a gas. The sputter chamber further includes a target substrate. A secondary material flexibly changes the composition of the target substrate in-situ by changing coverage of the target by the secondary material. Gas entering the sputter chamber interacts with the changed composition of the target. The interaction discharges a plasma alloy and the alloy condenses on the anode surface in the sputter chamber. The condensed alloy produces an alloy film.

  • Patent number: 9455361
    Abstract: Use of chemical mechanical polishing (CMP) and/or pure mechanical polishing to separate sub-cells in a thin film solar cell. In one embodiment the CMP is only used to separate the active, thin film layer into sub-cells, with scribing still being used to achieve sub-cell separation in conductive layers above and below the active, thin film layer. Also, the active layer may be placed over a series of protrusions so that the CMP removes the active layer that is over the protrusion, while leaving intact the flat, planar portions of the active layer. In this way, the removed active layer, from over the protrusions then becomes the division between sub-cells in the active layer.

  • Publication number: 20160240702
    Abstract: Manufacture of an improved stacked-layered thin film solar cell. The solar cell has reduced absorber thickness and an improved back contact for Copper Indium Gallium Selenide solar cells. The back contact provides improved reflectance particularly for infrared wavelengths while still maintaining ohmic contact to the semiconductor absorber. This reflectance is achieved by producing a back contact having a highly reflecting metal separated from an absorbing layer with a dielectric layer.

  • Publication number: 20150178651
    Abstract: Disclosed is an apparatus that includes an identifying module, a survey module, an analytics module, and a ranking module. The identifying module identifies selected users, wherein the selected users are those users that have an awareness of factors that potentially affect a supply chain. The survey module administers a supply chain screening survey, which includes groups of intercorrelated questions, to the selected users and receives survey answers from the selected users. The analytics module performs a modified Cronbach-alpha analysis on the survey answers from the selected users in order to generate a response consistency rating for each of the selected users. The modified Cronbach-alpha analysis includes determining, for each one of the selected users, consistency between selected users of the survey answers within each group of intercorrelated questions. The ranking module assigns a reliability rank to each of the selected users based on their response consistency rating.

    Abstract: An apparatus for building an information model for supply chain risk decision making includes a risk selection module, a priority module, a risk assessment module, and a scheduling module. The risk selection module selects, based upon a profiling questionnaire, one or more risk categories for an assessment subject. The priority module sets, based upon the profiling questionnaire, a level of importance of and a risk tolerance for the assessment subject in a supply chain. The risk assessment module receives, for each risk category of the one or more risk categories for the assessment subject, a likelihood and an impact of the risk category. The scheduling module sets a risk assessment schedule of the assessment subject based upon the level of importance of the assessment subject.
