High Efficiency p-i-n a-Si:H Solar Cells with Low Boron Cross-Contamination Prepared in a Large Area Single-Chamber PECVD Reactor

Christoph Hollenstein, Arvind Shah, Alan Howling, Cédric Bucher, Juliette Ballutaud, Stefano Benagli

In this work, a new type of short water vapor treatment of the interface between the p- and i-layer is presented. This novel treatment is performed under vacuum below 1 mbar for 5 min and considerably reduces the i-layer boron contamination in amorphous si ...

Micro-structured string-reactor for autothermal production of hydrogen

Albert Renken, Lioubov Kiwi, Chrystèle Horny

Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diam. of the channels (.apprx.100 mm) leads to a short radial diffusion time, a narrow residence time distribution, and a l ...

Planar and Tubular perovskite-type membrane reactors for the partial oxidation of methane to syngas

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Joseph Sfeir

Dense planar and tubular oxygen separation membranes of La 0.6Ca0.4Fe0.75Co0.25O3-d were investigated as reactors for the partial oxidation (POX) of methane to syngas. Disk-shaped membranes were prepared by compaction and tubes by extrusion. Their permeati ...

Loop reactor staged with structured fibrous catalytic layers for liquid-phase hydrogenations

Albert Renken, Lioubov Kiwi, Eric Joannet

A novel concept of a recycle loop reactor is developed with structured filamentous catalysts integrated as trays in a staged bubble column. The reactor can be operated in batch or continuous mode. Woven fabrics of activated carbon fibers (ACF) were used as ...

Simultaneous prediction of Cryptosporidium parvum oocyst inactivation and bromate formation during ozonation of synthetic waters

Urs von Gunten, Ji Hyun Kim

A model was developed to simultaneously assess Cryptosporidium parvum oocyst inactivation and bromate formation during ozonation of synthetic solutions in batch and flow-through reactors. The model incorporated 65 elementary chemical reactions involved in ...

Development of a novel microreactor-based calorimeter for the study of fast exothermal reactions in liquid phase

Marie-Agnès Schneider

Following several tragic chemical accidents that have occurred in recent years, some directives concerning chemical process safety have been issued. The Seveso directive, for example, requires a precise description of the consequences of a possible chemica ...

Reduction of the boron cross-contamination for plasma deposition of p–i–n devices in a single-chamber large area radio-frequency reactor

Christoph Hollenstein, Arvind Shah, Alan Howling, Cédric Bucher, Juliette Ballutaud, Stefano Benagli

In this article, a new treatment to reduce boron contamination of the interface between the p- and i- layer is presented. An ammonia flush, performed at 10 Pa for 1 min, after deposition of the p-layer considerably reduces the boron contamination at the p- ...

Measurement and interpretation of delayed photoneutron effects in multizone criticals with partial D2O moderation

Rakesh Chawla, Fabian Jatuff

The effective fraction of delayed photoneutrons (ph) has been theoretically defined and experimentally determined in various different configurations of the LWR-PROTEUS critical facility. The peculiarity lies in the fact that the reactor has D2O in only on ...

A stochastic model of an ozonation reactor

Urs von Gunten

Disinfection of some microorganisms is characterized by a lag-phase (a minimum required ozone exposure until disinfection occurs). This phenomenon is easy to model in laboratory batch reactors but not in continuous flow mixed reactors. This paper introduce ...
