  5. 8. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics

    Author : Per-Oskar Westin; Marika Edoff; Uwe Zimmermann; Lars Stolt; Friedrich Kessler; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser patterning; laser ablation; laser micro-welding; stability; Cu InGa Se2; CIGS; thin film solar cells; thin film photovoltaics; module technology; solar energy; Electronics; Elektronik; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    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

  6. 9. Three essays on transport CBA uncertainty

    Author : Peter Almström; Anders Karlström; Svante Berglund; Westin Lars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost-Benefit Analysis; Transport planning; Land-use planning;

    Abstract : Cost Benefit Analysis (CBA) has for a long time been used in transport planning, but it is often questioned. One main argument against CBA is that the results depend largely on assumptions regarding one or a few input factors, as for example the future fuel price or valuation of CO2 emissions. READ MORE

  7. 10. Empirical Essays on Procurement and Regulation

    Author : Magnus Arnek; Lars Westin; Uppsala universitet; []
