ZnO Transparent conductive oxide for thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Grégory Bugnon, Andrea Feltrin, Thomas Söderström, Sylvie Faÿ, Peter Cuony

There is general agreement that the future production of electric energy has to be renewable and sustainable in the long term. Photovoltaic (PV) is booming with more than 7GW produced in 2008 and will therefore play an important role in the future electric ...

Optimization of high efficiency silicon heterojunction solar cells using silane-plasma diagnostics

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf, Loris Barraud, Priscille Marguerite Bôle Rothen

In silicon heterojunction solar cells, the passivation of the crystalline silicon wafer surfaces and fabrication of emitter and back surface field are all performed by intrinsic and doped amorphous silicon thin layers, usually deposited by plasma-enhanced ...

Directed assembly of magnetic nanoparticles in polymers: The formation of anisotropic plastic films containing aligned nanowires

Raffaella Buonsanti

We present a facile technique for the prepn. of plastic films contg. aligned magnetic nanowires with anisotropic behavior. Solns. of magnetic nanoparticles mixed with polymers are drop casted on a substrate under the application of a weak magnetic field, a ...

Thermoresponsive polymers based on polyvinylpyrrolidone: applications in nanoparticle catalysis

Paul Joseph Dyson, Ning Yan, Yuan Yuan, Zhe Li

Two thermoresponsive polymers, poly(3-ethyl-1-vinyl-2-pyrrolidone) and poly(3-butyl-1-vinyl-2-pyrrolidone), with very sensitive and reversible temp.-dependent water soly. were described. The application of these polymers as Au nanocatalyst stabilizers lead ...

Bilayer hybrid solar cells based on triphenylamine-thienylenevinylene dye and TiO2

Ulf Anders Hagfeldt, Emilie Aude Marie Ripaud

Photoinduced energy conversion from multilayers of org. dye on dense TiO2 films was investigated in bilayer hybrid solar cells. Dye layers of varying thicknesses were prepd. by spin-casting the star-shaped dye [tris(dicyano-vinyl-2-thienyl)phenyl]amine fro ...

A hybrid solid-liquid polymer photodiode for the bioenvironment

Diego Ghezzi

We demonstrate that a prototypical semiconducting polymer, poly[2-methoxy-5-( 2′ -ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) maintains unaltered its optoelectronic properties throughout the various steps for neural preparation. Films of MEH-PPV, after ...

Combination of Polymer Technology and Carbon Nanotube Array for the Development of an Effective Drug Delivery System at Cellular Level

Silvestro Micera

In this article, a carbon nanotube (CNT) array-based system combined with a polymer thin film is proposed as an effective drug release device directly at cellular level. The polymeric film embedded in the CNT array is described and characterized in terms o ...
