MEMC Electronic Materials: Climbing the Wall of Worry

Based on the concept that metallurgical grade silicon (MG Silicon) lowers costs while reducing efficiency, it seems that there would be an optimum mix of solar grade silicon mixed with MG Silicon that would provide the optimum value for the consumer. In a broader perspective, the impurities in MG Silicon can be lowered with additional processing and cost. Again, there should be an optimum amount of refining that maximizes value to the consumer.
