  1. 1. Electrical analysis of interface recombination of thin-film CIGS solar cells

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Henrik Lotse; [2020]
    Keywords : interface recombination; SCAPS; activation energy; temperature dependent IV; dominant recombination path;

    Abstract : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).

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

    University essay from Uppsala universitet/Fasta tillståndets elektronik

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

    Abstract : 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.

  4. 4. Investigation of Metallic Dust formed on Steel Substrates in Solar Cell Sputtering Chambers

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jakob Friberg; [2019]
    Keywords : Sputtering; iron selenide; CIGS; solar cell; dust;

    Abstract : Investigations have been done as of why dust particles appear in a circular pattern on the backside of solar cells produced in sputtering chambers at Midsummer AB. An experimental approach was conducted, where solar cells were produced at standard conditions and their backside studied by material analytical methods. READ MORE

  5. 5. Processing of Sub-micrometer Features for Rear Contact Passivation Layer of Ultrathin Film Solar Cells Using Optical Lithography

    University essay from ;

    Author : Evelina Roxner; Ronja Olsmats Baumeister; [2019]
    Keywords : nanofabrication; optical lithography; photo lithography; line contacts; microfabrication; rear contact passivation; passivation layer; sub-micrometer features; thin film; ultra-thin film; solar cells; CIGS; aluminiumoxide;

    Abstract : Thin film copper, indium, gallium, selenide (CIGS) solar cells are promising in the field of photovoltaic technology. To reduce material and fabrication cost, as well as increasing electrical properties of the cell, research is ongoing towards ultra-thin film solar cells (absorption layer thickness less than 500 nm).
