  1. 1. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells

    Author : Zandra George; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; polymer interlayer; polymer solar cells; stability; conjugated polymers; fullerene derivatives;

    Abstract : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. READ MORE

  2. 2. Mass Transport Through Polymer Films: The Importance of Interfaces and Compatibility

    Author : Sofie Gårdebjer; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface modification; Interfaces; Compatibility; Polymer films; Cellulose; Barriers;

    Abstract : Different types of barriers are used in packaging to keep and protect products from the surrounding environment and are often essential for storing and transportation. Today, many barriers are made of different types of polymers, but since most polymers do not exhibit desired barrier properties on their own, combinations must be used. READ MORE
