Oxygen doping of P3HT:PCBM blends: Influence on trap states, charge carrier mobility and solar cell performance
Julia Schafferhans, Andreas Baumann, Alexander Wagenpfahl +2
We investigated the influence of oxygen on the performance of P3HT:PCBM (poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester) solar cells by current--voltage, thermal…
Comment on "Interface state recombination in organic solar cells"
C. Deibel, A. Wagenpfahl
In a recent paper, Street et al. [Phys. Rev. B 81, 205307 (2010)] propose first order recombination due to interface states to be the dominant loss mechanism in organic bulk hetero…
S-shaped current-voltage characteristics of organic solar devices
A. Wagenpfahl, D. Rauh, M. Binder +2
Measuring the current-voltage characteristic of organic bulk heterojunction solar devices sometimes reveals an s-shaped deformation. We qualitatively produce this behaviour by a nu…
Organic solar cell efficiencies under the aspect of reduced surface recombination velocities
A. Wagenpfahl, C. Deibel, V. Dyakonov
The charge carrier mobility is a key parameter for the organic bulk heterojunction solar cell efficiency. It was recently shown that the interplay charge carrier transport and reco…
