    Abstract : The use of solar cells for energy production has indeed a bright future. Reduction of cost for fabrication along with increased efficiency are key features for a market boom, both achieved as a result of increased knowledge of the technology. READ MORE

  4. 2. From Light to Dark : Electrical Phenomena in Cu(In,Ga)Se2 Solar Cells

    Author : Piotr Szaniawski; Marika Edoff; Uwe Zimmermann; Jörgen Olsson; Thomas Walter; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar cells; Photovoltaics; Cu InGa Se2; CIGS; Electrical characterization; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : In Cu(In,Ga)Se2 (CIGS) solar cells the CIGS layer serves as the light absorber, growing naturally p-type. Together with an n-type buffer layer they form a p-n heterojunction. Typically, CdS is used as a buffer, although other, less toxic materials are investigated as alternatives. READ MORE
