Dendritic Growth Furnace
Mono-Crystalline Ribbon, High Output Efficiency and Low Cost
Silicon Ribbon Puller
Thin single crystal silicon ribbon growth is based on the properties of dendritic growth and the formation of minimal surfaces. Two parallel dendrites up to 2" apart are pulled continuously from the silicon melt. A silicon web forms between them resulting in a ribbon of about 0.3 mm thickness used for the production of high efficiency solar cells.
The performance of these cells is indistinguishable from that of cells fabricated from Czochralski grown silicon. The wafering process is reduced to cutting the ribbon into pieces of appropriate length, which greatly reduces the overall cost of solar cells. GT Solar Incorporated designs and manufactures this furnace on exclusive basis for one customer. The complexity of the growth process with precise temperature and motion control demonstrates GT Solar's expertise to build complicated and fully automated production equipment.
This equipment was custom designed and manufactured by GT Solar Incorporated solely for its customers' use, and is not commercialized for resale.
