Ultralow secondary electron emission and improved vacuum surface insulation of polyimide with scalable nanocomposite coating

Chao Wang, Guang-Yu Sun

Polymers with high surface electric insulation capability are greatly demanded in various electrical devices operating in vacuum ambient. Low secondary electron emission (SEE) is favorable to mitigate vacuum flashover by inhibiting the SEE avalanche across ...

Modelling and Sensors for Magnetically-Levitated Disc Drives

Juan Patricio Tomás Peralta Fierro

The development of new industrial applications has diverted the focus of research towards compacter and faster rotatory drives. These requirements push the classical ball-bearings of electric motors to the limits in terms of operational lifetime and fricti ...

Integration of thin n-type nc-Si:H layers in the window-multilayer stack of heterojunction solar cells

Christophe Ballif, Mathieu Gérard Boccard, Luca Massimiliano Antognini, Julie Amandine Dreon, Vincent Philippe Paratte, Laurie-Lou Senaud

N-type nanocrystalline silicon (nc-Si:H(n)) layers are good candidates to improve current and transport properties in heterojunction solar cells. In this work, we perform thickness series alongside PH3 doping series to unravel the desirable characteristics ...

Employing 2D-Perovskite as an Electron Blocking Layer in Highly Efficient (18.5%) Perovskite Solar Cells with Printable Low Temperature Carbon Electrode

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Hobeom Kim, So-Min Yoo, Jaekeun Lim

Interface engineering and passivating contacts are key enablers to reach the highest efficiencies in photovoltaic devices. While printed carbon-graphite back electrodes for hole-transporting material (HTM)-free perovskite solar cells (PSCs) are appealing f ...

In-situ laser sintering for the fabrication of fully 3D printed electronics composed of elastomeric materials

Danick Briand, Rubaiyet Iftekharul Haque, Sébastien Lani, Ryan Mitchell van Dommelen

In-situ laser sintering can be used to locally sinter conductive inks in an uninterrupted process, enabling the embedding of printed electronics within 3D printed structures. In this work we apply a laser sintering method to create highly conductive silver ...

Recent progress in silk fibroin-based flexible electronics

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang

With the rapid development of the Internet of Things (IoT) and the emergence of 5G, traditional silicon-based electronics no longer fully meet market demands such as nonplanar application scenarios due to mechanical mismatch. This provides unprecedented op ...

Printed Polymer Composite Sensors for Low-Power, Near Room-Temperature Detection and Classification of VOCS

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

We demonstrate the application of inkjet-printed near room-temperature chemiresistors composed of polymer-carbon black (CB) composites for detecting and classifying volatile organic compounds (VOC). Our results demonstrate that the printed sensors can sele ...

Effect of electrode composition and patterning method on the lifetime of silicone-based dielectric elastomer actuators (DEA) under different environmental conditions

Herbert Shea, Fabio Beco Albuquerque

We report an experimental investigation of the lifetime of dielectric elastomer actuators (DEAs) under constant DC actuation, with a characterization setup which allows the monitoring of strain and resistance over time for 6 DEAs in parallel. We show how t ...
