Effect of Cs-Incorporated NiOx on the Performance of Perovskite Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Jiyoun Seo, Hui-Seon Kim, Monica Marcela Lira Cantu, Haibing Xie

The effect of Cs-incorporated NiOx on perovskite solar cells with an inverted structure was investigated, where NiOx and PCBM were used as selective contacts for holes and electrons, respectively. It was found that the generation of an Ni phase in an NiOx ...

A Robust Active Damping Control Strategy for an LCL-based Grid-connected DG Unit

Alireza Karimi, Aboutaleb Haddadi

The connection of a DG unit to a weak power system is challenging due to stability issues resulted from dynamic interactions between the DG unit and the grid. LCL-based DG unit is a particularly challenging case due to the presence of a high resonant peak ...

Phase and frequency self-configurable efficient low voltage harvester for zero power wearable devices

Pierre-André Farine, Alexis Boegli, Milad Ataei Ashtiani

This paper describes a converter which configures itself to increase power transfer and decrease losses. The system controls its three timing variables by three loops in a stable manner. A time domain state-space averaging model is used to design the syste ...

Temperature dependence of hydrogenated amorphous silicon solar cell performances

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Yannick Samuel Riesen

Thin-film hydrogenated amorphous silicon solar (a-Si:H) cells are known to have better temperature coefficients than crystalline silicon cells. To investigate whether a-Si:H cells that are optimized for standard conditions (STC) also have the highest energ ...

Heteroleptic Ru(II)-bipyridine complexes based on hexylthioether-, hexyloxy- and hexyl-substituted thienylenevinylenes and their application in dye-sensitized solar cells

A series of eight Ru(II) heteroleptic complexes incorporating an ancillary [2,2′]bipyridine functionalised at the [4,4′] positions with one (M-type) or two (B-type) thienylenevinylenes (nTVs, n = 2 or 4) is reported. Three types of substitutions have been ...

Analysis of the Maximum Efficiency of Kite-Power Systems

Dominique Bonvin, Grégory François, Sean Costello

This paper analyzes the maximum power that a kite, or system of kites, can extract from the wind. Firstly, a number of existing results on kite system efficiency are reviewed. The results that are generally applicable require significant simplifying assump ...

Complex image method for RF antenna-plasma inductive coupling calculation in planar geometry. Part I: basic concepts

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

The coupling between an inductive source and the plasma determines the power transfer efficiency and the reflected impedance in the primary circuit. Usually, the plasma coupling is analysed by means of a transformer equivalent circuit, where the plasma ind ...

Electroacoustic absorbers for the low-frequency modal equalization of a room: what is the optimal target impedance for maximum modal damping, depending on the total area of absorbers?

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar, Véronique Adam

Electroacoustic absorbers consist of loudspeakers, shunted with an electrical circuit designed to obtain a given acoustic impedance. Their design and principles are now well understood. Unidimensional experiments, using plane waves under normal incidence i ...
