MULTICRYSTALLINE SILICON INGOTS, SILICON MASTERALLOY, METHOD FOR INCREASING THE YIELD OF MULTICRYSTALLINE SILICON INGOTS FOR SOLAR CELLS

摘要

The present invention comprises directionally solidified multicrystalline silicon ingots, a silicon masteralloy for increasing the efficiency of solar cells made from wafers cut from the silicon ingots, method for increasing the yield when producing multicrystalline silicon ingots from a silicon melt by directional solidification. Further the present invention comprises a method for preparing said silicon masteralloy.
