  3. KANEKA Main Products at a Glance Foodstuffs and Life Science Products Bakery yeast, Margarine and shortening, Pharmaceutical bulk and intermediates PVC and Caustic Soda Polyvinyl chloride, Caustic Soda, Chlorinated PVC Electronic Products PV modules, Polyimide film, Magnet wire Functional Plastics Liquid polymer, Modified PET resins, Modifiers for plastics Synthetic Fibers Modacrylic fibers Expandable Plastics and Products Polyethylene/Polypropylene foam, Extruded polystyrene foam board, PVC sash window

  4. Capacity Expansion 130MW 70MW 55MW 30MW 20MW R&D 1980 1999 2006 2007 2008 2010 • Kaneka has been specializing in thin-film silicon technology: • 1980 Started study of a-Si technology • 1987 Participated in NEDO project (Government funded R&D) • 1999 Started 20MW/yr commercial production • Announced capacity expansion: • - up to 30MW in 2006, 55MW in 2007, 70MW in 2008 • Introduction of new Hybrid PV • Announced capacity expansion: up to 130MW in 2010

  5. Back Reflector Thin film mc-Si Bottom cell Transparent Interlayer a-Si Top cell Textured TCO Glass substrate Sun-Light B) New type HYBRID cell R&D of Advanced Device Structure Back Reflector Thin film mc-Si Bottom cell a-Si Top cell Textured TCO Glass substrate Sun-Light A) Conventional HYBRID cell

  6. Progress of Cell Efficiency (History and Plan) Active area conversion efficiency Conversion Efficiency (Initial) of 13.4% by newly developed interlayer on 5 Oct 2005 Under laboratory scale (measured by AIST) 15% New Technology 10% 5% products 1999 2005 present near future future Started overseas sales of Hybrid PV Started sales of Hybrid PV in JAPAN Started sales and mass-production of a-Si PV

  7. Manufacturing Plant KANEKA SOLARTECH CORPORATION (Hyogo, Japan) *Established 1998 *Capital US$ 29 million

  8. The production processes is highly automated for better quality and reliability.

  9. General Feature of thin film PV Comparing to standard crystalline Si PV… Target Market and Application Various Stand Alone Applications Big installation for Grid Connection Cheaper BOS cost/Wp due to scale economy. free installation space

  10. Long term experience (19 years/Japan) Site : Kobe Hyogo, Japan (N35, E135) Installation date : Jun. 1989 Still working well for power supply to ventilation fun

  11. Long term experience (7 years/Australia) Measured by JQA and Murdoch university Measured by JQA and Murdoch university No logged Only exposure No logged Only exposure Perth (31.6o S.L.) Darwin (12.5o S.L.)

  14. Long term experience (6 years/Italy) A-Si system has been exposed at Portici Italy from 2002. Degree C kWh/m2 or kWh/kWp No logged Only exposure Stable performance even near by seashore DC Production in 2007: 1354kWh/kWp AC Production in 2007: 1246kWh/kWp

  15. Experiences from Germany Hutschdorf (95349) 680kWp/South 30 degree Installed on 16.12.2004 Eurishofen (86860) 475kWp/South 30 degree Installed on 29.06.2004 2004: 930kWh/kWp 2005: 920kWh/kWp 2006: 933kWh/kWp 2007: 883kWh/kWp 2005: 1085kWh/kWp 2006: 1058kWh/kWp 2007: 1042kWh/kWp Hohestadt(97199) 475kWp/South 10 degree Installed on 29.09.2004 Koenigsmoos (86633) 130kWp/South 30 degree Installed on 12.01.2004 2004: 1043kWh/kWp 2005: 995kWh/kWp 2006: 1013kWh/kWp 2007: 1017kWh/kWp 2005: 948kWh/kWp 2006: 956kWh/kWp 2007: 912kWh/kWp

  16. Experiences from USA (1) System Overview Location:Arizona State University System Size:1,080Wp Panel Orientation:South Pitch:Approx. 30 degree

  17. (2) Annual Generated Output Power Data

  18. Accelerated Test Method Relative Module Efficiency years • *Long-term reliability data after full stabilization. • * Data measured by JQA usingKaneka’s a-Si Module, • supported by NEDO project.

  19. Irradiation strength (sun) Time (min.) Fig.1 Basic pattern of test Test conditions these accelerated test results harmonize with the results of actual 5 years’ outdoor test very well. You can see details of this test in the research report of NEDO. (No. 010016368) PV Temperature (degree C) 1 2 3 4 5 6 7 8 9 10 11 12 Corresponding months Fig.2 Test conditions of each month

  20. Going for Grid-Parity PV power generation cost competitive with traditional power generation
