  1. 1. Klimatutsläpp från Region Uppsalas solcellsanläggningar ur ett livscykelperspektiv

    University essay from SLU/Dept. of Energy and Technology

    Author : Bianca Nilsson; [2023]
    Keywords : livscykelanalys; energiplanering; solceller; jämförelse av solcellstekniker; klimatutsläpp; solcellspark;

    Abstract : Solceller är en del av en ny teknik för att kunna producera förnyelsebar energi som kan ersätta dagens fossila energikällor. Syftet med denna studie är att undersöka hur stora klimatutsläppen blir för de olika solcellsanläggningarna i Region Uppsala ur ett livscykelperspektiv, samt vilka faktorer som påverkar utsläppen.

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

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

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

    Abstract : 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.

  4. 3. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    University essay from Uppsala universitet/Solcellsteknik

    Author : Klara Kiselman; [2022]
    Keywords : Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Abstract : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  5. 4. 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).

  6. 5. 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.
