Origin of apparent light-enhanced and negative capacitance in perovskite solar cells

Ulf Anders Hagfeldt, Wolfgang Richard Tress, Firouzeh Ebadi Garjan

So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this c ...

Multiport Energy Gateway

Yan-Kim Tran

The global problem of energy supply and the reduction of the carbon footprint can only be solved by a massive replacement of fossil fuels or atomic energy by renewable resources. As the latter are mostly weather-dependent, they are uncontrollable and unpre ...

Cylindrical Dielectric Elastomer Actuator for Cardiac Assist Device

Jonathan André Jean-Marie Chavanne

This work has been triggered because of the need for a new way to relieve the heart. Current solutions are based on invasive systems. The main problem of such assistance is infectious risks. State of the art to define an alternative has allowed highlightin ...

Inverse Gating for Low Energy Block Ciphers

Francesco Regazzoni, Subhadeep Banik

In this paper we explore the technique of “inverse gating” which is a significant improvement over the ”round gating” technique introduced in HOST 2016. Round gating worked by generating timing signals to separate glitch propagation from one circuit elemen ...

Leakage Flux Modeling of Multi-Winding Transformers for System-Level Simulations

Drazen Dujic, Min Luo, Jost Allmeling

In multiwinding transformers, different geometry of the individual windings leads to unbalanced leakage flux paths. The unbalance affects the behavior of the power electronic converters, where these transformers are used. This paper proposes an approach to ...

On the Differential Input Impedance of an Electro-Explosive Device

In this paper, a model for the input impedance of a hot-wire electro-explosive device (EED) based on differential-mode measurements is proposed. The model represents the EED using three transmission line segments in cascade. The characteristics of each seg ...

Modeling Surface Recombination with Enhanced Devices Network for Optoelectronics

Jean-Michel Sallese, Pietro Buccella, Camillo Stefanucci, Chiara Rossi

We present a lumped devices network approach to simulate surface recombination effects in optoelectronics devices. The network is composed of generalized lumped devices where the excess carrier concentrations and gradients are mapped on electrical quantiti ...

Phase Corrected H-Plane Horn Antenna in Gap SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

This communication introduces a modified substrate integrated waveguide (SIW), the gap SIW, and deduces an approximate closed-form expression for calculating its effective width, taking into account the fringing and coupling fields around the gap. As an im ...
