  1. Solar Energy Terri Fiez Head & Professor, School of EECS Co-founder Azuray Technologies

  2. What Has Changed???? Unprecedented Growth in Population & Urbanization

  3. U.S. has 1/3 of the Worlds Vehicles and Uses ¼ of World’s Oil

  4. Tipping Point: The China Miracle

  5. U.S. Supplies 50% of its Energy with Coal China Supplies 80% of its Energy with Coal

  6. Are We Doomed?

  7. Innovation is Paramount to our Future Energy Security

  8. Clean Tech is Cool

  9. Why Solar? It’s Free!! • On a bright, sunny day, the sun shines approximately 1,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.

  10. How Does Solar Work? • Energy in the form of photons causes charges to be excited in a semiconductor – electrical current flows

  11. Mono-Crystalline Silicon Solar Cells(15-22% Efficient) Cross Section of Solar Cell Completed Solar Cell

  12. Other Solar Technologies Flexible Thin Film Polycrystalline Silicon Thin Film

  13. Solar Installations

  14. Balance of System • Everything but the Solar Panel • Wiring • DC-AC Converter • Combiner boxes • Racking & mounting • Etc.

  15. Solar Energy Conversion to Grid Today’s System Future System Micro-inverter DC AC AC Inverter Grid or User Grid or User

  16. Is Solar PV Too Expensive? What about government subsidies? Energy Tax Credits as much as 50% of system…

  17. Solar Cell Solar Module Systems Polysilicon Wafer Ingot $300/kg$30/kg 3 inches in diameter Now 8” Sawn one at a time Now < $0.25/W Thinner wafers: 15 mil → 10 mil 0.5 watts each3W $100/watt $1-$5/watt $200/watt $7/watt Solar from 1973 to TodayManufacturing from 1MW100MW Wafered Silicon Process Source Modified from: Dick Swansen, SunPower
