Long-term electrical characteristics of a poly-3-hexylthiophene water-gated thin-film transistor

Axel Luukkonen, Amit Tewari, Kim Björkström +5

Organic water-gated thin-film transistors (WG-TFTs) are of great interest in developing low-cost and high-performance biosensors. The device's sensitivity to changes in measurement…

Highly conductive charge transport layers impair charge extraction selectivity in thin-film solar cells

Mathias Nyman, Christian Ahläng, Staffan Dahlström +6

Charge selective interlayers are crucial in thin-film photovoltaics, such as organic and Perovskite solar cells. Charge transporting layers (doped and undoped) constitute perhaps t…

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…

Hysteretic magnetoresistance in polymeric diodes

Sayani Majumdar, Himadri S. Majumdar, Harri Aarnio +1

We report on hysteretic organic magnetoresistance (OMAR) in polymeric diodes. We found that magnitude and lineshape of OMAR depends strongly on the scan speed of the magnetic field…

Towards printed magnetic sensors based on organic diodes

Sayani Majumdar, Himadri S. Majumdar, Daniel Tobjork +1

We report the study of magnetotransport properties of regio-regular poly (3-hexyl thiophene) based organic diodes. The devices were fabricated using two different techniques of spi…
