9. Existing Solar Technologies • Silicon is the feedstock for 99% of solar • New technologies have not been able to bring relevant manufacturing scale • Focused on incremental cost reduction • Manufacturing processes are based on batched vacuum deposition in clean room • Capital and energy intensive manufacturing

10. Product Advantage Konarka Product Cost: 1/3 of traditional solar Form Factor: Power to Weight- 10x of traditional solar Thickness- 100x thinner than traditional solar Flexibility- conformable to 2 cm diameter Aesthetic- patterns, images and colors Cost Product Integration Form Factor • Product Integration: • Evolution from tethered to designed in • Designed into devices, systems, and structures

11. Periodic Table

12. Materials Used in Solar Cells • 99% of solar cells are based on Si • Very high purity materials used, similar to those used in the computer chip industry – requiring clean room atmospheres to process components • Other solar cells • Use Cu, In, Ga, Se, Cd, and Te • Vapor depositions are required

13. Major Chemical Feedstocks for Current Photovoltaic Manufacturing

14. Current Photovoltaic Manufacturing Requires: • Controlled distribution and handling systems • Rigorous safety controls and procedures • OSHA Process Safety Management • EPA regulations • Significant waste disposal costs • Downstream Electronic Take back / Reclamation

15. Materials Used By Konarka Konarka’s photovoltaic cells based on nano-engineered more environmentally acceptable materials Nano particles are used as an electrode within the solar cell resulting in a nano-structured framework similar to a “sponge” A connected matrix made of nano particles “frozen” in a macro-structure with very high surface area

16. Titania • Primary nano-particle used – TiO2 • Titanium dioxide (TiO2) is well known material used in numerous industries • Paint, Plastics, Catalysis, Coatings, Cosmetics, Ceramics, Toothpaste, Sunscreen • Titanium Dioxide is thermally stable, non toxic, and non-flammable

17. Konarka Manufacturing Process • No toxic chemicals All components have LD50 greater than 500mg/kg. • Uses environmentally friendly solvents with low emissions in manufacturing. • No known carcinogens

18. Partners - Venture and Corporate Venture Technology Ventures Ventures Corporate

19. Partners - Government and Labs University Wuppertal Government and Military Labs

20. Broad Visibility

21. Intellectual Property Portfolio • Over 250 patents and patent applications: • Materials • Process • Architecture • Devices • Global position

22. Business Strategy • Seed markets with production capacity • Provide functional materials to partners to better existing products • BASF & WL Gore model • Establish global manufacturing partners to leverage underutilized capacity • Enhance intellectual property estate • Develop partnerships around product applications

23. Executive Summary • Paradigm shift from silicon to plastic • Disruptive nanotechnology • Scalable roll-to-roll manufacturing process • Based on environmentally acceptable materials • Proven business model and strategy • Large rapidly growing global markets • Funded by tier-one VCs in US and Europe • Proven, experienced management team • World-class scientific team • Visibility on product and R&D revenue - 2005

24. A Common Vision For Our Future • For his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect. Albert Einstein(Nobel Prize for Physics, 1912) • I’d put money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that. • Thomas Edison(cited in Earth Island Journal, 7 / 2001) • Energy is the single most important problem facing humanity today. The alternative: energy from the sun and the Earth’s core. • Richard Smalley(cited in Small Times, 8 / 2002)
