    Abstract: A process for the manufacture of crystalline material 125 comprises: heating, using a first heat source 105, a first volume 130 of a ribbon 120 & 125, the ribbon comprising a polycrystalline material 120; and concurrently heating, using a second heat source 110 – A & hundred and 10 – B while the ribbon is moving relative to at least the second heat source and using the first heat source, a second volume 135 of the ribbon that is within the first volume, wherein heating using the first heat source and the second heat source converts at least a portion of the poly crystalline material of the ribbon within the second volume to a crystalline material. The first and second heat sources may be applied to different surfaces of the ribbon. The concurrent heating of the second volume may comprise scanning the second volume of the ribbon with the second heat source while the first volume and the second volume are heated by the first heat source. Also disclosed is a ribbon comprising a first volume extending from a first side of the ribbon to a first depth of the ribbon comprising a polycrystalline material; and a second volume extending from a second side of the ribbon opposite the first side to a second depth and comprising a crystalline material.
