  1. 1. Robust TCO’s for CIGS solar cells based on indium tin oxide

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Julia Nilsson; [2022]
    Nyckelord :photovoltaics; solar cells; thin film photovoltaics; PV; TCO; transparent conductive oxide; indium tin oxide; ITO; CIGS; solar power; sputtering; RF sputtering; radio frequency sputtering;

    Sammanfattning : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

  3. 2. Design Solution for Ingot Handling and Machining

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Johan Jönsson; [2021]
    Nyckelord :Mechanical Engineering; Product Development;

    Sammanfattning : At the electro remelting slag (ESR) facility at Uddeholm, cylindrical steel ingots are produced in several different sizes. The ESR process requires a “starting step” that consist of a 20mm thick steel plate and is a little larger than the diameter of the ingot. LÄS MER

  4. 3. AlP sacrificial layer for GaP NW growth

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Patrick Flatt; [2020]
    Nyckelord :Nanowire; Substrate Reuse; Sacrificial Layer; Epitaxy; Wafer; MOVPE; Etching; GaP; AlP; SiN; Au; SEM; Physics and Astronomy;

    Sammanfattning : III-V semiconductor nanowires (NWs) display outstanding potential for many technological applications, but their implementation into devices is restricted due to high material and fabrication costs. Common techniques for NW synthesis rely on single crystalline substrates, which are single-use and have large costs associated to them. LÄS MER

  5. 4. Merging Electrohydrodynamic Printing and Electrochemistry : Sub-micronscale 3D-printing of Metals

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Marcus Lindén; [2017]
    Nyckelord :additive manufacturing; 3D-printing; microsystem; nanotechnology; nanoscale; EHD; electrochemical; metals;

    Sammanfattning : Additive manufacturing (AM) is currently on the verge of redefining the way we produce and manufacture things. AM encompasses many technologies and subsets, which are all joint by a common denominator; they build three dimensional (3D) objects by adding materials layer-upon-layer. LÄS MER

  7. 5. Intressentens inflytande En studie av intressenternas roll vid kalkmålningskonserveringen i Barsebäcks kyrka, utifrån tekniska, formella och värdemässiga perspektiv.

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Kajsa Nyström Rudling; [2013-11-26]
    Nyckelord :Wall paintings; Mural paintings; Stakeholders; Conservation; Value assessment;

    Sammanfattning : This master’s thesis aim to examine the roles of different stakeholders within a conservation process and how they are influenced by technical, formal/legal and value based concerns. This is done through a case study of mural painting conservation in the church of Barsebäck. LÄS MER
