  • Publication number: 20150024542
    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: 20140202529
    Abstract: A silicon solar cell is manufactured by providing a carrier plate, and by applying a first contact pattern to the carrier plate. The first contact pattern includes a set of first laminar contacts. The silicon solar cell is further manufactured by applying a multitude of silicon slices to the first contact pattern, and by applying a second contact pattern to the multitude of silicon slices. Each first laminar contact of the set of first laminar contacts is in spatial laminar contact with maximally two silicon slices. The second contact pattern includes a set of second laminar contacts. Each second laminar contact of the set of second laminar contacts is in spatial laminar contact with maximally two silicon slices.

  • Publication number: 20140102509
    Abstract: Manufacture for an improved stacked-layered thin film solar cell. 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.

  • Patent number: 8631565
    Abstract: A method for manufacturing a solar concentrator cell module assembly within an integrated circuit process, which solar concentrator cell module assembly includes at least one solar device and which solar device includes one printed circuit board and one Fresnel lens. A printed circuit board is assembled according to a pre-defined circuit board base design layout that allows pick and place of a single solar concentrator cell chip onto a circuit board base. Connections are provided for the solar concentrator cell chip in a serialized or a parallelized arrangement on the circuit board base, and a plurality of openings are formed in the circuit board base below a backside of the solar concentrator chip to enable attachment of cooling fingers.

  • Publication number: 20130226652
    Abstract: Embodiments of the invention relate to identification of risks in a brand commodity supply chain. Risks are centrally assessed and a single holistic image of the risk assessment is provided. Specifically, risks are assessed vertically and horizontally across the supply chain, brand, and commodity. Risk identification techniques may be applied to the identified risks to reduce supply chain disruption and to enable continued manufacturing.

    Abstract: A computer-implemented method for providing on-demand manufacturing execution systems for clients in which a response to a questionnaire from a client with information relative to identification of a business and production process, a determination of process steps, and an identification of process step requirements is evaluated by the service provider according to GUI requirements for each one of a number of individual process steps. Based on the evaluation, a GUI is defined for each of the individual process steps by the service provider and provided to the client for installation on client computing devices in a manufacturing line of the client. Data is collected for each of the individual process steps via each GUI and sent to the service provider for storage and evaluation.
