  1. 1. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Joel Johansson Byberg; [2019]
    Nyckelord :CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  2. 2. Selective Electron Exctraction in Nanowire-based Solar Cells

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Klára Nováková; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The transmission function for a three and four rectangular barrier system of InP andInAs is computed using the transfer-matrix method and the transmission formalism. Thewidths of the wells and the barriers are varied while the barrier height is kept constant. LÄS MER

  3. 3. Aerial Thermography Inspections in Large-Scale PV Plants

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Salvador Selva Marti; [2018]
    Nyckelord :Infrared thermography inspection; large-scale PV plants; drone; unmanned aerial vehicles; Quintas Energy; operation and maintenance; monitoring operations;

    Sammanfattning : In order to successfully compete against the use of fossil fuels to generate electricity, one of the challenges in the photovoltaic (PV) business currently in focus is on the asset management of large PV plants, in which developing control techniques to prognosticate and evaluate the future energy performance will be essential. Infrared thermography inspections can give meaningful support to assess the quality and performance of PV modules. LÄS MER
