2. 1. Recycling of selenium from CIGS solar cell materials

   Author : Anna Gustafsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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

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

   Author : Ulf Malm; Marika Edoff; Lars Stolt; James R. Sites; Uppsala universitet; []
   Keywords : 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
