Abstract	L'evolution de la production mondiale de cellule photovoltaique a entraine une penurie en silicium de haute purete. Le silicium de qualite moindre provoque, lors de la cristallisation, l'apparition de morphologies indesirables (grits) dues a la precipitation de carbure et de nitrure de silicium. Cependant les parametres physico-chimiques lies a ces phenomenes sont encore inconnus. Dans ce but, nous avons developpe une experience de levitation electromagn etique sous ultra vide permettant de mesurer la surfusion de germination du silicium en presence de carbone et d'azote dans des conditions controlees. Les resultats ont montre une diminution drastique de la surfusion en augmentant la concentration en impurete. En parall ele un modele de transition facette-equiaxe a ete developpe. En s'appuyant sur des modeles analytiques, il permet de predire les transitions colonnaires-grits au cours de la solidication d'un lingot ainsi que la repartition en taille des grains dans les zones de grits.
