Encounter-Limited Charge Carrier Recombination in Phase Separated Organic Semiconductor Blends
Michael C. Heiber, Christoph Baumbach, Vladimir Dyakonov +1
The theoretical effects of phase separation on encounter-limited charge carrier recombination in organic semiconductor blends are investigated using kinetic Monte Carlo (KMC) simul…
Nongeminate recombination in neat P3HT and P3HT:PCBM blend films
Julien Gorenflot, Michael C. Heiber, Andreas Baumann +5
The slow decay of charge carriers in polymer-fullerene blends measured in transient studies has raised a number of questions about the mechanisms of nongeminate recombination in th…
Effects of Characteristic Length Scales on the Exciton Dynamics in Rubrene Single Crystals
Björn Gieseking, Teresa Schmeiler, Benjamin Müller +4
As for its inorganic counterparts the future developments in organic electronics are driven by an advanced device miniaturization. Therefore, the opto-electronic behavior of up-to-…
Shockley Equation Parameters of Organic Solar Cells derived by Transient Techniques
A. Foertig, J. Rauh, V. Dyakonov +1
The Shockley equation (SE), originally derived to describe a p--n junction, was frequently used in the past to simulate current--voltage (j/V) characteristics of organic solar cell…
Impact of nongeminate recombination on the performance of pristine and annealed P3HT:PCBM solar cells
Markus Gluecker, Alexander Foertig, Vladimir Dyakonov +1
Transient photovoltage (TPV) and voltage dependent charge extraction (CE) measurements were applied to poly(3-hexylthiophene)(P3HT):[6,6]-phenyl-C61 butyric acid methyl ester (PCBM…
Excitation Dynamics in Low Band Gap Donor-Acceptor Copolymers and Blends
Björn Gieseking, Berthold Jäck, Eduard Preis +5
Donor-acceptor (D-A) type copolymers show great potential for the application in the active layer of organic solar cells. Nevertheless the nature of the excited states, the couplin…
