Impact of a doping-induced space-charge region on the collection of photo-generated charge carriers in thin-film solar cells based on low-mobility semiconductors
Oskar J. Sandberg, Staffan Dahlström, Mathias Nyman +3
Unintentional doping of the active layer is a source for lowered device performance in organic solar cells. The effect of doping is to induce a space-charge region within the activ…
Method for characterizing bulk recombination using photoinduced absorption
Nora M. Wilson, Simon Sandén, Oskar J. Sandberg +1
The influence of reaction order and trap-assisted recombination on continuous-wave photoinduced absorption measurements is clarified through analytical calculations and numerical s…
Correlation between Organic Magnetoresistance (OMAR) and Ferromagnetic ordering
Sayani Majumdar, Himadri Majumdar, Jan-Olof Lill +3
We report observation of ferromagnetic (FM) ordering in organic semiconductors, namely regio-regular poly (3-hexyl thiophene) (RRP3HT) and 1-(3-methoxycarbonyl)propyl-1-phenyl-[6,6…
Hopping conduction in strong electric fields: Negative differential conductivity
A. V. Nenashev, F. Jansson, S. D. Baranovskii +3
Effects of strong electric fields on hopping conductivity are studied theoretically. Monte-Carlo computer simulations show that the analytical theory of Nguyen and Shklovskii [Soli…
The role of electron-hole recombination in organic magnetoresistance
Sayani Majumdar, Himadri S Majumdar, Harri Aarnio +3
Magneto-electrical measurements were performed on diodes and bulk heterojunction solar cells (BHSCs) to clarify the role of formation of coulombically bound electron-hole (e-h) pai…
