EpiWafers
NexWafe uses Kerfless Wafer Technology for the production of monocrystalline silicon wafers. The resultant EpiWafers are a drop-in replacement for Cz wafers in solar cell production.
Pilot
Kerfless monocrystalline silicon wafers
High quality mono-crystalline n-type silicon wafer. Full-square instead of semi-square. Very low thickness variations. Very narrow resistivity distribution. Drop-in solution.
The need
PV module costs have to be reduced. 40% of PV module costs are associated with the cost of the wafer. Current wafer manufacturing processes have a very limited cost reduction potential. Disruptive technologies are needed to bring wafer costs down.
The solution
NexWafe uses Kerfless Wafer Technology for the production of high quality mono-crystalline n-type silicon wafers. EpiWafers are an economical drop-in replacement for Cz wafers in solar cell production. Full-square instead of semi-square, they have very low thickness variation and extremely narrow resistivity distribution.
The value proposition
• Cost saving.
• High solar cell efficiencies.
• Higher power.
