  1. Introduction • Some Definitions • What is a “Solar Cell” or Photovoltaics” (PV) • Just a Little About Materials and Designs

  2. Some Definitions • Solar Cell • Solar Panel • Solar Array

  3. What is a Solar Cell

  4. What’s a Solar Panel

  5. What’s a Solar Array

  6. What is a “Solar Cell” or “Photovoltaics” (PV) - (Single Layer Design)

  7. Multi-Layer Solar Cell Design

  8. Most Panels Are Made of Semiconductor Grade Silica

  9. Some Are On Flexible Stainless Steel

  10. Most Are Placed In Frames…

  11. Some Are Unframed as Slates…

  12. …or Shingles

  13. Some Are Laminated To Steel Roofing…

  14. …or Attached To Clear Glass

  15. Solar Power

  16. Uses And Applications From Around The World

  17. In August Of 1954 This Ad Appeared In National Geographic

  18. The Text Below Said….

  19. One of the early uses – of “Solar Cells” was Telestar in 1962…..

  20. ….. and one of the more recent uses of solar panels is space station “Freedom”

  21. Some earth bound uses of solar power are well known to us all….

  22. …. and many uses are in remote areas, far away from our power plants and the electric power “Grid”

  23. In the tropics, where the electric power infrastructure does not exist ….

  24. …solar power can be very useful.

  25. …. and in Africa, very far from the nearest electric pole.

  26. To many, solar power is still a curiosity,

  27. or something really ugly that belongs somewhere out in the “back 40.”

  28. Is this an “alien craft”?

  29. Is this a modern work of art?

  30. A backyard picnic table?

  31. ...or part of a fraternity initiation?

  32. No, it is a solar powered car!

  33. …and here is another one. Unfortunately, there are some problems with these cars….

  34. Along with solar cars, there are solar busses,

  35. and solar busses…

  36. there are even solar bus shelters.

  37. There are solar trucks,

  38. and solar trucks.

  39. There were even solar rechargeable electric cars(formerly manufactured by General Motors).

  40. There are companies who make solar golf carts,

  41. and individuals who make solar airplanes,

  42. as well as the solar powered road sign trailers that we have all seen.

  43. There even are some solar powered median barriers.

  44. Here are some smaller solar lighting applications,

  45. and some more,

  46. …and solar being used at one very remote location.

  47. Some manufacturers have built solar electric powered boats,

  48. in different sizes and in some unusual shapes.

  49. People have built some unusual structures to hold their solar panels,
