Homojunction-induced thermopower enhancement in polymer films
Zhen Xu, Hui Li, Guangzheng Zuo +7
It has been more than twenty years since conductive polymers began to receive attention as an emerging thermoelectric material. However, the trade-off between electrical conductivi…
Composition Anisotropy Drives Large Bulk Photovoltaic Fields Along the Non-polar Vertical Direction in 2D Hybrid Perovskite Ferroelectrics
Yuzhong Hu, Andrii Shcherbakov, Jonathan Zerhoch +7
The photovoltaic electric field of the bulk photovoltaic effect (BPE) reflects the intrinsic ability of ferroelectrics to separate photoexcited excitons into electrons and holes, a…
Direct Measurement of the Effective Electronic Temperature in Organic Semiconductors
Anton Kompatscher, Martijn Kemerink
Organic semiconductors show complex phenomena due to their high energetic disorder. A striking example is the possibility of an increased effective temperature T_eff of the charge…
Soft Coulomb Gap Limits the Performance of Organic Thermoelectrics
Yuqian Liu, Xiaoran Wei, Dorothea Scheunemann +4
Although consensus exists that the thermoelectric properties of doped organic semiconductors result from a complex interplay between a large number of mutually dependent factors, t…
Ion-Exchange Doping of Semiconducting Single-Walled Carbon Nanotubes
Angus Hawkey, Aditya Dash, Xabier RodrÃguez-MartÃnez +6
Semiconducting single-walled carbon nanotubes (SWCNTs) are a promising thermoelectric material with high power factors after chemical p- or n-doping. Understanding the impact of do…
Hot Carrier Organic Solar Cells
Priya Viji, Constantin Tormann, Clemens Göhler +1
Hot-carrier solar cells use the photon excess energy, that is, the energy exceeding the absorber bandgap, to do additional work. These devices have the potential to beat the upper…
