Instability of p-i-n perovskite solar cells under reverse bias

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Arnaud Walter, Daniel Anthony Jacobs, Ricardo Augusto Zanotto Razera, Sylvain Nicolay, Laura Ding, Fan Fu, Chien-Jen Yang, Peter Joseph Fiala, Marion Solange Madeleine Dussouillez

Partial shading can trigger permanent damage in photovoltaic modules because the illuminated solar cells drive the shaded cells into reverse bias. Under reverse bias conditions, perovskite solar cells have been shown to degrade quickly due to processes tha ...

Grouping and “objecthood” effects in the Ebbinghaus illusion

Michael Herzog, Aline Françoise Cretenoud, Einat Rashal

We examined the effect of grouping processes on the Ebbinghaus illusion by manipulating objecthood: the degree to which an object is perceived as a cohesive entity. We presented observers with squares as targets and inducers and manipulated the degree of t ...

Locating lightning strikes and flashovers along overhead power transmission lines using electromagnetic time reversal

Mario Paolone, Gianluca Antonini, Reza Razzaghi, Keyhan Sheshyekani, Marco Scatena

The paper presents a method to identify the location of direct lightning strikes to overhead transmission lines and potential subsequent flashover(s). The method is based on the electromagnetic time reversal theory and relies on the use of a single measure ...

Gas Sensor with Reduced Humidity Response, Based on Metal Oxide Nanoparticles Synthesized by Spark Discharge

Thomas Maeder

The most part of gas sensors based on tin dioxide semiconductor sensing material are fabricated by using sol-gel synthesis of SnO2. This process leads to the formation of highly sensitive sensing material; however, it forms hydroxyl groups on the surface o ...

Gate Leakage Tunneling Impact on the InAs/GaSb Heterojunction Electron-Hole Bilayer Tunneling Field-Effect Transistor

Mihai Adrian Ionescu, José Luis Padilla de la Torre

Among the different types of bilayer tunneling field-effect transistors exploiting interband tunneling phenomena with tunneling directions aligned with gate-induced electric fields, the utilization of InAs/GaSb channels proves to be an appealing means to e ...

The effect of “objecthood” in the Ebbinghaus illusion

Michael Herzog, Aline Françoise Cretenoud, Einat Rashal

In the Ebbinghaus illusion, observers overestimate the size of a target when it is surrounded by large flakers and compared with a control target surrounded by small flankers. We examined whether “objecthood” – the degree to which an object is a cohesive e ...

A Switched Oscillator Geometry Inspired by a Curvilinear Space-Part II: Electrodynamic Considerations

This is the second part of a two-part paper in which we present a new technique for the design of coaxial switched oscillators (SWOs). In this part, we present a model for the analysis of the signal radiated by the SWO, in both frequency and time domains. ...

Surface trap mediated electronic transport in biofunctionalized silicon nanowires

Giovanni De Micheli, Sandro Carrara, Francesca Puppo, Massimiliano Di Ventra

Silicon nanowires (SiNWs), fabricated via a top-down approach and then functionalized with biological probes, are used for electrically-based sensing of breast tumor markers. The SiNWs, featuring memristive-like behavior in bare conditions, show, in the pr ...

Spark discharge synthesis of semiconductor nanoparticles for thick-film metal oxide gas sensors

Thomas Maeder

Traditional methods of synthesis of metal-oxide gas sensing materials for semiconductor sensors are based on wet sol-gel processes. However, these processes lead to the formation of hydroxyl groups on the surface of oxide particles being responsible for th ...

Influence of ground wire on the initiation of upward leader from 110 to 1000kV AC phase line

Xi Wang, Rong Zeng

The problem of upward leader inception from transmission lines has not been thoroughly discussed, largely because of the difficulty to obtain experimental data under natural circumstances. Previous studies have primarily examined reduced-scale experiments ...
