Hole transporting materials for perovskite solar cells and a simple approach for determining the performance limiting factors

Mohammad Khaja Nazeeruddin, Tom Theodorus Antonius Lummen, Iwan Zimmermann

The synthesis and characterization of three novel HTMs with different highest occupied molecular orbital (HOMO) energy levels and their performances in MAPbI(3)-based devices in comparison with Spiro-OMeTAD is reported. Without systematic optimization, the ...

Time-resolved open-circuit conductive atomic force microscopy for direct electromechanical characterisation

Anna Fontcuberta i Morral, Jelena Vukajlovic Plestina, Wonjong Kim

Studying nanomaterial piezoelectricity and triboelectricity is attractive for energy and sensing applications. However, quantitative characterisation of electromechanical effects in nanomaterials is challenging due to practical limitations and possible com ...

IGCT Based Solid State Resonant Conversion

Dragan Stamenkovic

Driven by the environmental changes, penetration of renewables and the need for more flexible power grid, DC is reemerging as a basis for future power networks. Already established in the area of HVDC for very long distance transmission, more and more atte ...

Electrical energy generated by silicone elastomers filled with nanospring- carbon- nanotubes

Frank Nüesch

Dielectric elastomer generators (DEGs) are flexible capacitors that convert mechanical into electrical energy. They rely on an external voltage source to charge the capacitor during each operation cycle. An alternative to this is an autonomous DEG which op ...

Yttrium zinc tin oxide high voltage thin film transistors

Herbert Shea, Danick Briand, Alexis Pierre Henri Marette

We demonstrate that doping the semiconductor zinc tin oxide (ZTO) with yttrium leads to a high-voltage thin film transistor (HVTFT) with enhanced switching performance. Adding 5% yttrium leads to an increase in the on-off ratio from 40 to 1000 at an operat ...

A Reliability and Efficiency Optimization System for Hard-Switching DC/DC Converters

Maher Kayal, Federico Faccio, Adil Koukab, Stefano Michelis, Giacomo Ripamonti

The Large Hadron Collider experiments at CERN will use power distribution schemes relying on integrated buck DC/DC converters. Due to the radiation-hardness requirements, the devices used for the development of such converters will have a voltage rating wh ...

Design techniques for a stable operation of cryogenic field-programmable gate arrays

Edoardo Charbon, Harald Arjan Robert Homulle

In this paper, we show how a deep-submicron field-programmable gate array (FPGA) can be operated more stably at extremely low temperatures through special firmware design techniques. Stability at low temperatures is limited through long power supply wires ...
