  2. 1. Conjugated polymers for optoelectronics

    Author : Lars Johan Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer Light-Emitting Diodes; Conjugated polymers; Polyfluorenes; Polymer Solar Cells;

    Abstract : The work presented in thesis is divided into two parts; conjugated polymers for light-emitting diodes and conjugated polymers for solar cells. The main focus was on the synthesis and characterisation of the conjugated polymers, together with device preparation and characterisation. READ MORE

  4. 2. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

    Author : Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

    Abstract : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

  5. 3. Synthesis of Conjugated Polymers for Solar Cell Applications

    Author : Desta Antenehe Gedefaw; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polyfluorenes; Conjugated polymers; Donor-acceptor miscibility; Black polymers; Optical absorption;

    Abstract : Fossil fuels are largely used as a source of energy to fulfil the energy demand of mankind. However, fossil fuels suffer from limitations. The unlimited burning of fossil fuels releases greenhouse gases and causes environmental pollution. Fossil fuels are also an unreliable source of energy since the natural deposit is limited.

  6. 4. Vertical charge transport in conjugated polymers

    Author : Vasyl Skrypnychuk; Alexandr Talyzin; Ellen Moons; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic electronics; conjugated polymers; nanotechnology; nanoimprint lithography; graphene; P3HT; charge transport; X-ray diffraction; structure; crystallite orientation; Materials Science; materialvetenskap;

    Abstract : Conjugated polymers are novel organic electronic materials highly important for organic photovoltaic applications. Charge transport is one of the key properties which defines the performance of conjugated polymers in electronic devices. READ MORE

  7. 5. Photoluminescence in Conjugated Polymers : Experimental Investigations of Excited State Events

    Author : Mathias Theander; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : After an extensive scientific effort spent on the understanding of conjugated polymers and molecules, these material are on the border of commercialisation. Even though highly efficient devices can be made with conjugated polymers the underlying physics is far from being fully understood. READ MORE
