The document discusses solar power technologies, including solar water heating, concentrating solar power, and photovoltaic (PV) cells. It explains the operation of solar power towers that use focused sunlight to heat a fluid, generating steam to power turbines. Additionally, it describes the basic functioning of photovoltaic cells, where absorbed sunlight excites electrons in silicon to generate electricity.
Solar Power Science and Projects
- 4. Concentrating Solar Power Photovoltaic (PV) Cells
- 7. Sunlight focused on heat transfer fluid (HTF), which then runs steam turbine
- 9. Basic process by which a photovoltaic cell converts absorbed sunlight into electricity “Photons” knock electrons free from the silicon structure, freeing them to enter electric current and power a “load” (like a light bulb)
