  2. 11. A study of devices and materials for polymer based LEDs

    Author : Jonas Birgerson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjugated; polymer; XPS; LED; Magnesium; blend; copolymer;

    Abstract : Since the discovery that it is possible to dope conjugated polymers into high electrical conductivity the research in the field of conjugated polymers has increased a lot. Much of the research activity has been concentrated to the design and fabrication of light emitting devices. READ MORE

  4. 12. Conjugated Polymer-based Conductive Fibers for Smart Textile Applications

    Author : Tariq Bashir; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-active fibers; poly 3; 4-ethylenedioxythiophene PEDOT ; viscose; polyester; chemical vapor deposition CVD process; electrical characterizations; smart textiles; stretch sensor; Organic Electronics; Smart Textiles; textile yarns; Textiles and Fashion General ; Textil och mode generell ;

    Abstract : Electrically conductive or electro-active fibers are the key components of smart and interactive textiles, which could be used in medical, sports, energy, and military applications in the near future. The functionalization of high-performance textile yarns/fibers with conjugated polymers can produce conductive fibers with better electro-mechanical properties, which is difficult with commonly used spinning techniques.

  5. 13. 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

  6. 14. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors

    Author : Petri Henrik Murto; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solution processing; conjugated polymers; fluorescence; near-infrared; light-emitting electrochemical cell; organic photodetector; organic light-emitting diode;

    Abstract : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.

  7. 15. Morphology and material stability in polymer solar cells

    Author : Rickard Hansson; Ellen Moons; Andreas Opitz; Mats Fahlman; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer solar cell; photovoltaics; morphology; photo-degradation; conjugated polymer; fullerene; synchroton-based techniques; Physics; Fysik;

    Abstract : Polymer solar cells are promising in that they are inexpensive to produce, and due to their mechanical flexibility have the potential for use in applications not possible for more traditional types of solar cells. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor material in the active layer. READ MORE
