  2. Brief History of Solar Cells • Dates back to French physicist Antoine-Cesar Becquerel of 1839 . • He observed that shining light on an electrode submerged in a conductive solution would create an electric current. • By 1941 Russell Ohl had invented the first silicon solar cell. • The energy crisis of the 1970s sparked an interest but the prices were too high. • Now they are becoming more cost effective.

  3. Building Integrated Photovoltaic (BIP) • Integrate solar cells with buildings. • They are in the form of photovoltaic panels. • They are used in walls, roofs, and in “Power Glass”. • Sunlight strikes the panels and create electricity that is used in conjunction with the electricity supplied by local energy companies.

  4. BIPV Process • Place a very thin, semi-transparent coating and film over a large area of glass or transparent plastic. • Use a reel-to-reel manufacturing technique to create the film. • This coating will replace conventional glazing material and at the same time create electricity.

  5. Used on windows, atrium glazing, roof glazing, or curtain walling BIP are especially useful in today’s commercial and industrial facilities. Applications
