High thermoelectric power factor of poly(3-hexylthiophene) through in-plane alignment and doping with a molybdenum dithiolene complex
Viktoriia Untilova, Jonna Hynynen, Anna I. Hofmann +8
Here we report a record thermoelectric power factor of up to 160 W m-1 K-2 for the conjugated polymer poly(3-hexylthiophene) (P3HT). This result is achieved through the combina…
How to Reduce Charge Recombination in Organic Solar Cells: There Are Still Lessons to Learn from P3HT:PCBM
Sebastian Wilken, Dorothea Scheunemann, Staffan Dahlström +3
Suppressing charge recombination is key for organic solar cells to become commercial reality. However, there is still no conclusive picture of how recombination losses are influenc…
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…
