Silicon ingot and wafer quality depend on the silicon feedstock, crucible, furnace materials and the parameters of the crystallization process.
The introduction of the Steuler reusable ceramic crucible liberates the crystallization process from its current design constraints, making possible new furnace concepts that enable ingots to be produced continuously, rather than in batches. This reduces feedstock to as-grown ingot conversion costs by 50%.
Fundamental problems associated with traditional quartz crucibles are rapidly becoming a limiting factor in further efficiency improvements as solar cell efficiency continues to increase.
The Steuler Solar reusable ceramic crucibles and the improved crystallization processes they make possible set a new quality standard for ingots and wafers.
