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

    University dissertation from Stockholm : KTH

    Author : Desta Antenehe Gedefaw; [2010]
    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.

    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

  5. 5. Conjugated polyelectrolytes : conformation sensitive optical probes for the recording of biological processes

    University dissertation from Linköping : Linköpings universitet

    Author : Peter Nilsson; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The physical properties of conjugated polymers can be utilized for a wide range of biosensors. For instance, the conformational flexibility fouud in conjugated polyelectrolytes, allows direct connection between the geometry of chains and the resulting electronic structure and optical processes, since the extension of the π-conjugated system is distorted by conformational changes of the polyelectrolyte backbone.
