Sammanfattning : 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. LÄS MER
Sammanfattning : 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.

Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
