  1. 1. Recycling of CIGS solar cell waste materials

    Author : Anna Gustafsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrometallurgy; Pyrometallurgy; CIGS; Recycling; Solar cells;

    Abstract : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. READ MORE

  2. 2. 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

    Abstract : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. 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. Highly Efficient CIGS Based Devices for Solar Hydrogen Production and Size Dependent Properties of ZnO Quantum Dots

    Author : T. Jesper Jacobsson; Tomas Edvinsson; Laurence Peter; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanoparticles; Quanum Dots; Size Dependent Properties; Hematite; CIGS; Solar Water Splitting; Hydrogen Production; PEC; Photoelectrochemical cells; PV-electrolysis; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Materials and device concepts for renewable solar hydrogen production, and size dependent properties of ZnO quantum dots are the two main themes of this thesis.ZnO particles with diameters less than 10 nm, which are small enough for electronic quantum confinement, were synthesized by hydrolysis in alkaline zinc acetate solutions.
