Spire’s solar cell turnkey lines provide lowest cost of ownership and produce highest efficiency solar cells. The solar cell factories retain a throughput of 2,400 wafers per hour which reduces the overall operating cost of a factory. The operating cost of the factory is lowered significantly by:

There are many benefits to partnering with Spire for a solar cell factory including

• Top of the line equipment selection with a proven track record
• Unprecedented solar cell and factory expertise
• Single point of contact
• Integrated process control and quality controls
  • Automated robotic inspection at each loader
  • Off-line sampling inspections at random
• No manual handling of wafers or cells reducing breakage
• 98% mechanical and electrical yield
• Yield enhancement tools with advanced technology options available

There are many options available to further enhance a solar cell line and increase the overall throughput.

• Multi-crystalline or mono-crystalline solar cell production
• Production capacity up to 300MW based on customer needs
• Selective Emitter Formation
• High precision screen printing including double printing
• Ink Jet printing
• Silver on silver (Ag) Light Induced Plating (LIP)
• Copper stack (Cu, Ni) plating
• Metallization Wrap Through (MWT)
• Emitter Wrap Through (EWT)
