Contact Resistivity Measurements and their Applicability for Accurate Series Resistance Breakdown in Heterojunction Solar Cell

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Laurie-Lou Senaud, Deniz Türkay, Matthieu Despeisse, Mathieu Gérard Boccard, Lison Sylou Marthey, Luca Massimiliano Antognini, Julie Amandine Dreon

In this work, we use several approaches to perform accurate Series Resistance (R-S) breakdown of a state of the art 2 cm x 2 cm screen-printed solar cell reaching 82.5% FF. On the one hand, Haschke et al.'s model for the lateral transport through the cell, ...

Sondheimer oscillations as a probe of non-ohmic flow in WP2 crystals

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Yi-Chiang Sun, Jonas De Jesus Diaz Gomez, Maarten Ruud van Delft, Jacopo Oswald

As conductors in electronic applications shrink, microscopic conduction processes lead to strong deviations from Ohm's law. Depending on the length scales of momentum conserving (l(MC)) and relaxing (l(MR)) electron scattering, and the device size (d), cur ...

Kinetic approach to the Schwinger effect during inflation

Oleksandr Sobol

Using the kinetic approach, we study the impact of the charged particle dynamics due to the Schwinger effect on the electric field evolution during inflation. As a simple model of the electric field generation, we consider the kinetic coupling of the elect ...

Applicability of Non-Destructive Examination to Iter TF Joints Nb3Sn

Pierluigi Bruzzone, Stephen Alfred March

The Iter TF joints are of a twin-box design and the critical parameters of the overall resistance are 1) the contact between cable and termination, and 2) the resistance between two terminations. This paper describes applicability of non-destructive examin ...

Electron and Hole Mobilities in Single-Layer WSe2

Andras Kis, Adrien Victor Allain

Single-layer transition metal dichalcogenide WSe2 has recently attracted a lot of attention because it is a 2D semiconductor with a direct band gap. Due to low doping levels, it is intrinsic and shows ambipolar transport. This opens up the possibility to r ...
