  2. 6. Modelling Band Gap Gradients and Cd-free Buffer Layers in Cu(In,Ga)Se2 Solar Cells

    Author : Jonas Pettersson; Charlotte Platzer-Björkman; Marika Edoff; Marc Burgelman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CIGS; Thin film solar cells; Electrical modelling; Alternative buffer layers; Gallium gradients; Simulations; Electrical characterization; Metastabilities; Light-soaking; Hall measurements; Persistent photoconductivity; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : A deeper understanding of Cu(In,Ga)Se2 (CIGS) solar cells is important for the further improvement of these devices. This thesis is focused on the use of electrical modelling as a tool for pursuing this aim. Finished devices and individual layers are characterized and the acquired data are used as input in the simulations. READ MORE

  4. 7. Wafer Bonding for Spaceflight Applications : Processing and Characterisation

    Author : Kerstin Jonsson; Maaike Visser-Taklo; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; wafer bonding; oxygen plasma; wet chemical; anodic bonding; gamma irradiation; proton irradiation; temperature cycling; vibration; shock; Weibull; adhesion quantification; double cantilever beam; tensile; chevron; blister; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. READ MORE

  5. 8. Optimization Capabilities for Crushing Plants

    Author : Kanishk Bhadani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Key Performance Indicators KPIs ; Crushing; Digital Twin; Modelling; Calibration; Multi-Disciplinary Optimization MDO ; Dynamic Simulations; Multi-Objective Optimization MOO ; Screening; Process Optimization; Process Improvement; Production Data;

    Abstract : Responsible production and minimal consumption of resources are becoming competitive factors in the industry. The aggregates and minerals processing industries consist of multiple heavy mechanized industrial processes handling large volumes of materials and are energy-intensive. READ MORE

  6. 9. PENSIERI - An Inquiry into Sketching and Modelling in Design

    Author : Maral Babapour Chafi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Physical and Digital Modelling; Sketching; Design Activities; Concept Generation; Product Representations;

    Abstract : When proposing ideas for design solutions, designers often make representations, for example sketches and models of different kinds. This thesis seeks to examine what designers do when interacting with different media to externalise their ideas, and the resources they have at their disposal. READ MORE

  7. 10. Anthropometric diversity and consideration of human capabilities : Methods for virtual product and production development

    Author : Erik Brolin; Roland Örtengren; Dan Högberg; Lars Hanson; John Rasmussen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; Human Factors; Anthropometry; Multi-Dimensional; Diversity; Digital Human Modelling; Simulation; Visualisation; Workplace Design; Product Design; Accommodation; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

    Abstract : Contemporary product and production development is typically carried out with the support of computer tools where the design of products and workstations are originated and evaluated within virtual environments. Ergonomics addresses factors important to consider in the product and production development process to ensure a good fit between humans and the items being designed. READ MORE
