Abstract

Patente de Invenção: <B>''PROCESSO DE PRODUçãO DE SILìCIO PARA USO EM CéLULAS SOLARES''<D>. Processo para produção de silício altamente purificado para uso em células solares por um processo de solidificação única, vazando silício um mole e gradualmente solidificando fracionalmente o mesmo, enquanto atentando para a solidificação da superfície líquida, seguida por purificação do silício solidificado por fusão por zona ou aplicação de fundição contínua usando um molde eletromagnético, por fusão por zona, em combinação com fundição contínua e, opcionalmente, induzindo solidificação direcional para concentrar as impurezas, lixiviação e reciclagem.
