1. Optical modelling of conjugated polymers : from materials to devices
Abstract : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.

2. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level
Abstract : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. READ MORE

4. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment
Abstract : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. READ MORE

5. Synthesis and Properties of Conjugated Polymers for Photonic Devices
Abstract : The synthesis and properties of new conjugated polymers for photonic devices, such as light-emitting diodes and solar cells is dealt with here. Much work was devoted to increasing the efficiencies of the devices by controlling the properties in thin films of the polymers. READ MORE
