  2. 16. Electrically Conducting Yarns for Electronic Textiles

    Author : Sozan Darabi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Electronic textiles (e-textiles) present a huge opportunity to incorporate wearable devices into textiles. Electrically conducting yarns and fibers can be utilized to create these e-textiles. For e-textiles to be wearable the development of electrically conducting yarns needs to rely on materials that are neither scares nor toxic. READ MORE

    Abstract : Nowadays, there is an urgent need to decrease our dependence on fossilresources and shift towards the use of renewable resources for advancingsustainable development. Utilizing renewable and bio-based raw materials,such as lignocellulosic biomass, for designing new materials is a promisingapproach to promote this objective. READ MORE

  6. 19. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells

    Author : Zandra George; Chalmers tekniska högskola; []
    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

  7. 20. Synthesis and properties of pi-conjugated polymers for organic photovoltaics

    Author : Renee Kroon; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic photovoltaics; structure-property relationships; Conjugated polymers; energy level engineering;

    Abstract : Organic photovoltaics is a renewable energy technology able to solve global warming and the upcoming energy gap, issues that both originate from fossil fuel consumption. Out of all renewable energy sources, the Sun is the only source that produces enough energy to fulfill all our energy needs, now and in the future. READ MORE
