  1. 1. Optical Efficiency of Low-Concentrating Solar Energy Systems with Parabolic Reflectors

    Författare :Maria Brogren; Arne Roos; Björn Karlsson; Andreas Häberle; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Photovoltaic cells; Photovoltaic-thermal systems; Parabolic reflectors; Optical properties; Reflector materials; Optical efficiency; Accelerated ageing; Outdoor ageing; Building-integrated photovoltaics; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : Solar electricity is a promising energy technology for the future, and by using reflectors for concentrating solar radiation onto photovoltaic cells, the cost per produced kWh can be significantly reduced. The optical efficiency of a concentrating system determines the fraction of the incident energy that is transferred to the cells and depends on the optical properties of the system components.

  4. 3. Chargeand Light Management in Organic Solar Cells

    Författare :Zheng Tang; Olle Inganäs; René Janssen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Solar cells based on organic materials are extensively investigated both in academia and industry, owing to their potential of being inexpensive, lightweight, flexible and suitable for roll-to-roll production. Performance of organic solar cells has been rapidly improving, and the state of the art organic solar cells have an efficiency over 10%. LÄS MER

  5. 4. Fill factor of organic solar cells and applications of dilute donor devices

    Författare :Nannan Yao; Fengling Zhang; Jonas Bergqvist; Jan van Stam; Weimin Chen; Julia W. P. Hsu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic solar cells (OSCs) have attracted great attention due to their low cost, flexibility and solution-processibility. In recent years, the development of nonfullerene acceptors (NFAs) has truly promoted the efficiency of OSCs up to 19%, implying high potential for commercial applications. LÄS MER
