Transient optical and electrical effects in polymeric semiconductors
… extraction under linear increasing voltages (CELIV) is investigated in some detail, correcting for errors in the published approach and highlighting the role of non-idealized conditions typically present in experiments. An improved method is suggested to determine the field dependence of …

Elementary processes in layers of electron transporting Donor-acceptor copolymers : investigation of charge transport and application to organic solar cells
… of charge carrier trapping on the shape of photo-CELIV and time-of-flight transients is discussed. In addition, the high performance naphthalenediimide (NDI)-based copolymer P(NDI2OD-T2) was characterized. It is shown that the copolymer posses one of the highest electron mobilities reported so …

Perylene Diimide Molecular Glass: Investigations of Charge Transport
A new glass-forming organic semiconductor material was synthesized using a known electron transport material, perylene diimide, and attaching it to a molecular glass in order to allow the material to be solution processed. Devices were made using a simple metal-semiconductor-metal structure and …
