摘要： A system for producing a ribbon from a melt includes a crucible to contain a melt and a cold block. The cold block has a surface that directly faces an exposed surface of the melt. A ribbon is formed on the melt using the cold block. A furnace is operatively connected to the crucible. The ribbon passes through the furnace after removal from the melt. The furnace includes at least one gas jet. The gas jet can dope the ribbon, form a diffusion barrier on the ribbon, and/or passivate the ribbon. Part of the ribbon passes through the furnace while part of the ribbon is being formed in the crucible using the cold block.
