  1. 1. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Aravind Srinivasachari; [2023]
    Nyckelord :Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

    Sammanfattning : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

  3. 2. Air and Silicon resistivity design space for dielectric simulations

    Kandidat-uppsats,

    Författare :Oscar Hammarberg; Anton Larsson; Adam Steiner; [2022]
    Nyckelord :electrical bushings; simulations; humidity; electrical breakdown; corona discharge; comsol multiphysics;

    Sammanfattning : Electrical bushings are a type of hollow or solid conductor withinsulation designed to allow a conductor to pass through a conductingbarrier without making electrical contact and are very important forsafe transportation of electricity. The bushings vary in size, but allbushings have a solid or hollow conductor. LÄS MER

  4. 3. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Edvin Nilsagård; Rebecka Knutsson; [2022]
    Nyckelord :ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Sammanfattning : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. LÄS MER

  5. 4. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Linnéa Bendrot; [2022]
    Nyckelord :Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER

  7. 5. Magnetron sputtering of transparent conducting tungsten doped indium oxide

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Erica Evertsson; [2022]
    Nyckelord :sputtering; indium; TCO; tungsten; thin film; solar cell; IOW;

    Sammanfattning : In thin film solar cells there is a front contact layer called TCO, transparent conducting oxide. This layer requires high conductivity and high transmittance. LÄS MER
