  1. Photovoltaic Cells Boris Krassovski Emerson Peacock 6th Period

  2. What are Photovoltaic Cells? • PV Cells use solar power to create energy • PV Cells are use in calculators, on satellites and to power our own homes http://www.princeton.edu/~chm333/2002/spring/SolarCells/images/pv%20cells.jpg

  3. The goals of PV cells • Like all alternative sources of energy, the main goal of PV cells is to replace fossil fuels as the main source of energy • Another goal is to use the abundant sunlight as an alternative due to its endless amounts

  4. Potential in Making a Difference • Since sunlight is endless and very abundant PV cells have very high potential to be a primary source of energy • It also creates jobs and strengthens the economy since it is a brand new industry • PV cells are very reliable and costs little to build and operate

  5. How it works and functions • Solar cells directly convert sunlight into energy • A magnetic field is created that forces electrons to move and that is what we consider electricity • Output of PV cells depends on weather and the time of day

  7. Technological Obstacles • Batteries are required to store the electricity produced by PV cells which adds maintenance problems • Power is only produced during daytime and highly depends on the weather http://www1.eere.energy.gov/solar/utility_scale.html

  8. Political and Economic Obstacles • Large scale Photovoltaic plants are costly and cost more to maintain than conventional power plants • Batteries that are added in order to store the power produced are also very high costing http://www1.eere.energy.gov/solar/pv_use.html

  9. Environmental Impacts • There are no negative environmental impacts with the use of PV cells because no wastes are emitted • Sunlight is highly abundant and free to use therefore PV cells are very good for the environment • PV cells is one of the cleanest alternative power sources available
