    Sammanfattning : Copper has in its heavier chalcogenides often a high mobility in the solid state. This behaviour has also be found for some ternary compounds where copper appears to govern the observed phase transitions and structural transformations. LÄS MER

  2. 2. First-Principles Study on Electronic and Optical Properties of Copper-Based Chalcogenide Photovoltaic Materials

    Sammanfattning : To accelerate environmentally friendly thin film photovoltaic (PV) technologies, copper-based chalcogenides are attractive as absorber materials. Chalcopyrite copper indium gallium selenide (CIGS ≡ CuIn1–xGaxSe2) is today a commercially important PV material, and it is also in many aspects a very interesting material from a scientific point of view.
