Experimentally Calibrated Kinetic Monte Carlo Model Reproduces Organic Solar Cell Current-Voltage Curve
Sebastian Wilken, Tanvi Upreti, Armantas Melianas +5
Kinetic Monte Carlo (KMC) simulations are a powerful tool to study the dynamics of charge carriers in organic photovoltaics. However, the key characteristic of any photovoltaic dev…
On occupation times of one-dimensional diffusions
Paavo Salminen, David Stenlund
In this paper we study the moment generating function and the moments of occupation time functionals of one-dimensional diffusions. Assuming, specifically, that the process lives o…
Watching Space Charge Build up in an Organic Solar Cell
Sebastian Wilken, Oskar J. Sandberg, Dorothea Scheunemann +1
Space charge effects can significantly degrade charge collection in organic photovoltaics (OPVs), especially in thick-film devices. The two main causes of space charge are doping a…
A high-throughput and data-mining approach to predict new rare-earth free permanent magnets
Alena Vishina, Olga Yu. Vekilova, Torbjörn Björkman +3
We present an application of a high-throughput search of new rare-earth free permanent magnets focusing on 3d-5d transition metal compounds. The search involved a part of the ICSD…
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…
Scaling and diabatic effects in quantum annealing with a D-Wave device
Phillip Weinberg, Marek Tylutki, Jami M. Rönkkö +5
We discuss quantum annealing of the two-dimensional transverse-field Ising model on a D-Wave device, encoded on lattices with . Analyzing the residual energy…
