Despite significant improvement in power conversion efficiencies of bulk-heterojunction solar cells, the mechanism of mobile charge carrier generation is still under debate. The time-resolved microwave conductivity technique is used to investigate th

Using THz time domain spectroscopy, we investigate ultrafast photoconductivity in two conjugated polymers, derivatives of poly(phenylene vinylene) (MEH-PPV) and polythiophene (RR-P3HT), to investigate free charge carrier dynamics. We find that the ul

A model to calculate the mobility of charges along molecular wires is presented. The model is based on the tight-binding approximation and combines a quantum mechanical description of the charge with a classical description of the structural degrees

The effect of the chain length of conjugated polymers on the real and imaginary components of the frequency dependent mobility of charge carriers is studied. A theoretical model for one-dimensional diffusive motion of charges between reflecting chain

This paper describes a quantum chemical study of the electronic structure of thienylene vinylene oligomers ranging in size from two thienylene rings (2TV) to 12TV. The geometries of the TV oligomers in the ground state, the lowest triplet state, and

We show the results of positron beam Doppler broadening measurements on low-density polyethylene under external electric fields. It is found that long-term measurements with a moderate beam intensity of approximately 10 5 e + /s result in the accumul

The Doppler broadening of annihilation radiation (DBAR) technique and UV-Vis photo-absorption spectroscopy were used to monitor the photo-oxidation of thin films (200 nm) of OC1OC10-PPV. Samples were exposed in air to a 308 nm excimer laser and a com
