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.
