  1. 1. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells

    Author : Hannes Michaels; Marina Freitag; Aldo Di Carlo; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Coordination chemistry; energy conversion; photovoltaics; charge transport;

    Abstract : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. READ MORE

  2. 2. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices

    Author : Kristofer Tvingstedt; Olle Inganäs; Peter Peumans; Linköpings universitet; []
    Keywords : Light trapping; Organic solar cells; Tandem cells; Polymer solar cells; Plastsolceller; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. READ MORE

  3. 3. III-V Nanowire Solar Cells: Growth and Characterization

    Author : Gaute Otnes; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Solar cell; Photovoltaic; Metal organic vapor phase epitaxy; Nanoimprint lithography; Electron beam induced current; Current-voltage characteristics; Doping; Fysicumarkivet A:2018:Otnes;

    Abstract : To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. READ MORE

  4. 4. Modelling and Degradation Characteristics of Thin-film CIGS Solar Cells

    Author : Ulf Malm; Marika Edoff; Lars Stolt; James R. Sites; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar cells; thin-film; chalcogenide; stability; characterization; modelling; simulations; finite element method; CIGS; photovoltaic module; Electronics; Elektronik;

    Abstract : Thin-film solar cells based around the absorber material CuIn1-xGaxSe2 (CIGS) are studied with respect to their stability characteristics, and different ways of modelling device operation are investigated. Two ways of modelling spatial inhomogeneities are detailed, one fully numerical and one hybrid model. READ MORE

  5. 5. Recycling of selenium from CIGS solar cell materials

    Author : Anna Gustafsson; Chalmers University of Technology; []
    Keywords : CIGS; Recycling; Thin film; Photovoltaic; Solar cells;

    Abstract : Today the importance of solar cells as a power source is growing due to the environmental advantages compared to fossil fuels. One of the most promising new solar cell materials, resulting in high efficiency solar cells, is copper indium gallium selenide (CIGS). READ MORE
