Production Prototype Development

• DOE I I Project with AVA Tech
• System for semiconductor processing nominal 2
  MW/yr.
• Modules installed for beta testing
• Participants
• - Colorado State University Engineering is a
  subcontractor
• - NSC/Acheson is partner
• - CSU Facilities system engineering, beta
  testing
• K. Barth PI,
• (Sampath will discuss technical results in
  "short presentations" )

By 2006 demonstrate nominal 2 MW/yr. prototype
production semiconductor processing system and
install modules for beta testing.

NSC Partnership

• I. NSC/Acheson
• Specialty electronic coatings electrode for our
  PV devices supplied by Acheson Ind. part of
  National Starch and Chemical (NSC)
• NSC is the US subsidiary of the approx. 10
  Billion/yr, ICI Group
• Tremendous experience in polymers/coatings
  technology
• II. I and I partnership
• Provide 50 cost share
• Engineer and develop electrode application system

series interconnection (7) Lamination and
encapsulation
By end of I I project Steps 2,4 and 5 at a
nominal 2 MW/yr throughput, other processing
steps performed at lower throughput by outside
vendors
