Defect passivation in zinc tin oxide: improving the transparency-conductivity trade-off and comparing with indium-based materials

Oscar Esteban Rucavado Leandro

Transparent conductive oxides (TCOs) are essential in technologies coupling light and electricity. Due to their good optoelectronic properties and the production scalability, Sn-doped indium oxide (In2O3:Sn) is the preferred TCO in industrial applications. ...

Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Raphaël François Lemerle

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density

Corrosion mechanisms and durability models for historical tinplate food cans

Fabio Cova Caiazzo

Since the early of the 19th century, canning is one the most efficient ways to preserve foods. Tinplated steel has been used since the beginning for this purpose and it is still one of the most used materials for cans production because it combines the goo ...

Print-Light-Synthesis of Platinum Nanostructured Indium-Tin-Oxide Electrodes for Energy Research

Andreas Stephan Lesch

Print-light-synthesis is a new concept for the large-scale in situ fabrication of nanoparticles and structures on large substrates. Here, Pt nanoparticles are synthesized on indium tin oxide (ITO) coated glass slides by using combined inkjet printing and p ...

Yttrium zinc tin oxide high voltage thin film transistors

Danick Briand, Herbert Shea, 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 ...

Highly Active and Stable Iridium Pyrochlores for Oxygen Evolution Reaction

Nicola Marzari

Proton exchange membrane water electrolysis (PEMWE) is a promising technology for electricity-to-fuel conversion which allows for direct production of hydrogen from water. One of the key problems limiting widespread implementation of PEMWE into energy syst ...

Solution-Processed Tin-Based Perovskite for Near-Infrared Lasing

Michael Graetzel

The family of solution-processed tin-based perovskites is demonstrated as a new and superior near-infrared gain medium. Due to the large electron-hole bimolecular recombination associated with tin and the reduced trap density with SnF2 treatment, these lea ...

Design strategy for controlled natural aging in Al-Mg-Si alloys

William Curtin

This study presents a design strategy for Al-Mg-Si alloys to control natural aging. Recently, trace addition of Sn was shown to suppress natural aging for up to two weeks, which was explained by the strong trapping of vacancies to Sn atoms. Here we explore ...

Fully inkjet printed SnO2 gas sensor on plastic substrate

Nico de Rooij, Danick Briand, El Hadji Malick Camara

A tin dioxide (SnO2) sensor was fabricated by inkjet printing onto polyimide foil. Gold electrodes and heater were printed on each side of the substrate. A SnO2 based ink was developed by sol-gel method and jetted onto the electrodes. A final annealing at ...

Supramolecular assemblies of organotin(IV)-diphosphoryl adducts: insights from X-rays and DFT

Kurt Schenk

Mono-, di- and tri-phenyltin(IV) adducts containing a neutral diphosphoryl ligand, Ph2P(O)OC6H4OP(O) Ph-2, were synthesized and characterized. These 2 : 1 adducts of two trans-organotin(IV) moieties and the bridging ligand all crystallize around a centre o ...
