ABSTRACT Work on silicon crystal quality improvement and defect control has been carried out lab‐scale seeded growth ingots allowing wafers with controlled grain orientations. Both <111> <100> monocrystalline‐like were produced using a combination of quartz rod dipping modulated conductive heat extraction system, made in‐house, in directional solidification system. Two mono‐like wafer morphology types have produced. Their structural electrical properties are presented detail....
La liaison interfaciale entre un metal pur non reactif et oxyde iono-covalent (isolant) est generalement assuree par de faibles interactions type physique (van der Waals) chimique (etats electroniques interfaciaux faible densite). Par consequent, mauvais mouillage observe, caracterise angle contact superieur a 90 o . Un moyen d'ameliorer le rajouter, dans une matrice metallique, solute B capable modifier favorablement l'interface metal/oxyde. Cet effet obtenu via deux mecanismes, dependant...
The presented work is part of the French PHOTOSIL project which deals with purification metallurgical grade (MG) silicon to obtain Solar Grade (SoG) by a combination innovative refinement/up-grading techniques such as segregation and plasma purification. main objectives this are production costs <;15€/kg, photovoltaic performance >15% solar cell efficiencies, material yields >85% after crystallization. In paper we present latest results obtained intensely purified via modified process....
