Experimentally Validated Hopping-Transport Model for Energetically Disordered Organic Semiconductors
Tanvi Upreti, Yuming Wang, Huotian Zhang +3
Charge transport in disordered organic semiconductors occurs by hopping of charge carriers between localized sites that are randomly distributed in a strongly energy dependent dens…
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…
Rubbing and Drawing: Generic Ways to Improve the Thermoelectric Power Factor of Organic Semiconductors?
Dorothea Scheunemann, Vishnu Vijayakumar, Huiyan Zeng +4
Highly oriented polymer films can show considerable anisotropy in the thermoelectric properties leading to power factors beyond those predicted by the widely obeyed power law linki…
Non-Wiedemann-Franz Behavior of the Thermal Conductivity of Organic Semiconductors
Dorothea Scheunemann, Martijn Kemerink
Organic semiconductors have attracted increasing interest as thermoelectric converters in recent years due to their intrinsically low thermal conductivity compared to inorganic mat…
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…
