Space charge behaviours in polyethylene under combined AC and DC electric fields
, 2014 Polyethylene has been one of the widely studied polymeric insulation materials. One of the major issues related to polymeric materials is the easy formation of space charge which may cause electric field enhancement. In this paper, a numerical simulation

The rate of charge recombination in Photosystem II
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2002 Loss by recombination of the charge separated state P(680+)Q(A-) limits the performance of Photosystem II (PS II) as a photochemical energy converter. Time constants reported in literature for this process are mostly either near 0.17 ms or near 1.4 ms.

Temperature Dependence of Ultra‐Exothermic Charge Recombinations [PDF]
ChemPhysChem, 2006 AbstractWe measured the temperature dependence (from +32 to −50 °C) of charge‐recombination rates between contact radical ion pairs in isopropyl ether. In the systems selected for this study, aromatic hydrocarbon cations are the electron acceptors and the fumaronitrile anion is the electron donor.

Subnanosecond Charge Recombination Dynamics in P3HT/PC61BM Films
Molecules, 2012 Ultrafast near-infrared absorption spectroscopy was used to investigate the influence of film morphology and excitation photon energy on the charge recombination (CR) dynamics in the initial nanosecond timescale in the P3HT/PC61BM blend films.

The Effect of Ketone Defects on the Charge Transport and Charge Recombination in Polyfluorenes
Advanced Functional Materials, 2011 AbstractThe effect of on‐chain ketone defects on the charge transport of the polyfluorene derivative poly(9,9‐dioctylfluorene) (PFO) is investigated. Using MoO3 as ohmic hole contact, the hole transport in a pristine PFO diode is observed to be limited by space‐charge, whereas fluorenone contaminated PFO (PFO‐F) is shown to be trap limited by the ...
