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…
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…
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…
Investigation of the Spatially Dependent Charge Collection Probability in CuInS/ZnO Colloidal Nanocrystal Solar Cells
Dorothea Scheunemann, Sebastian Wilken, Jürgen Parisi +1
Solar cells with a heterojunction between colloidal CuInS and ZnO nanocrystals are an innovative concept in solution-processed photovoltaics, but the conversion efficiency cann…
Effect of Imbalanced Charge Transport on the Interplay of Surface and Bulk Recombination in Organic Solar Cells
Dorothea Scheunemann, Sebastian Wilken, Oskar J. Sandberg +2
Surface recombination has a major impact on the open-circuit voltage () of organic photovoltaics. Here, we study how this loss mechanism is influenced by imbalanced ch…
Semitransparent Polymer-Based Solar Cells with Aluminum-Doped Zinc Oxide Electrodes
Sebastian Wilken, Verena Wilkens, Dorothea Scheunemann +4
With the usage of two transparent electrodes, organic solar cells are semitransparent and may be combined to parallel-connected multi-junction devices or used for innovative applic…
Role of Oxygen Adsorption in Nanocrystalline ZnO Interfacial Layers for Polymer-Fullerene Bulk Heterojunction Solar Cells
Sebastian Wilken, Jürgen Parisi, Holger Borchert
Colloidal zinc oxide (ZnO) nanoparticles are frequently used in the field of organic photovoltaics for the realization of solution-producible, electron-selective interfacial layers…
