Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

open access: yesAdvanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

From Laboratory to Industry: Evaporating Functional Layers at High Rates for Fully Textured Perovskite/Silicon Tandems

open access: yesAdvanced Energy Materials, EarlyView.
Perovskite/silicon tandem solar cells exhibit outstanding efficiencies; however, the development of scalable and high‐throughput manufacturing processes remains a critical challenge. Here, we demonstrate accelerated deposition of multiple functional layers via high‐rate thermal evaporation without compromising film quality or device performance.

On the molecular interaction between albumin and ibuprofen: An AFM and QCM-D study

open access: yesColloids and Surfaces B: Biointerfaces, 2015
The adsorption of proteins on surfaces often results in a change of their structural behavior and consequently, a loss of bioactivity. One experimental method to study interactions on a molecular level is single molecular force spectroscopy that permits to measure forces down to the pico-newton range. In this work, the binding force between human serum
