Abstract:
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.

Claim (Index 8):
A method of preparing the silicon masteralloy according to  claim 7  for increasing of multicrystalline silicon ingots, the method comprising adding elemental calcium to a molten high purity silicon in an amount chosen from at least one of the following ranges: 0.5-20 weight %, 1-15 weight %, 5-15 weigh t%, homogenizing the resulting alloy and solidifying said alloy to provide said silicon masteralloy.
