   Sammanfattning : The main part of the thesis is concerned with charge photogeneration in conjugated polymers. MeLPPP and POMeOPT films were investigated by transient absorption spectroscopy using different excitation photon energies and light intensities with and without an external electric field. LÄS MER

3. 2. Non-Equilibrium Charge Motion in Organic Solar Cells

   Författare :Armantas Melianas; Olle Inganäs; Martijn Kemerink; Jenny Nelson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Organic photovoltaic (OPV) devices based on semiconducting polymers and small molecules allow for a low cost alternative to inorganic solar cells. Recent developments show power conversion efficiencies as high as 10-12%, highlighting the potential of this technology. Nevertheless, further improvements are necessary to achieve commercialization.
