Solar Energy-Solar Panel lesson with activity.pptx

Solar panels, also known as photovoltaic (PV) panels, are devices designed to convert sunlight directly into electricity through the photovoltaic effect. They are composed of numerous solar cells made of semiconductor materials, typically silicon, which can generate electricity when exposed to sunlight.

4. What is a solar panel? It is also known as Photovoltaic cell (PV cell) A device that converts light energy (solar energy) directly to electricity. The term solar cell is designated to capture energy from sunlight, whereas PV cell is referred to an unspecified light source. It is like a battery because it supplies DC power, It is not like a battery because the voltage supplied by the cell changes with changes in the resistance of the load . Solar Cells are Made from a single crystalline silicon wafer .

6. Success Criteria: HS-PS4-5 Communicate the cause-and-effect relationships in devices that use the photoelectric effect to produce electric current. Photovoltaic effect and solar Cell The photovoltaic effect occurs when light from the Sun, which is made up of packets of energy called photons, falls upon a solar panel and generates an electric current .

Photoelectric effect and Photovoltaic Effect What is the difference between photovoltaic and photoelectric effect? The main difference between photoelectric effect and photovoltaic effect is that in photoelectric effect, the electrons are emitted to open space whereas in photovoltaic effect, the electrons enter a different material

12. How the solar panel working? Solar cells transfer energy from the photons in sunlight to the electrons in the solar cell. The more photons of sunlight absorbed by the solar cell, the greater the electric current. That’s why the short-circuit current depends so strongly on the orientation of the solar cell. The maximum voltage, on the other hand, is fixed by the material the solar cell is made of. Solar cells also have an internal resistance, which reduces the voltage available at the terminals when current flows.

13. How the solar panel working? The solar cell has energy losses, so does not covert 100% of the solar power to electricity. Some of the light is reflected from the surface of the solar cell, and some of the light is blocked by the metal lines on top of the solar cell that conduct electricity through the cell. To make a solar cell more efficient, the manufacturers reduce reflected light and minimize cell shading by keeping the area of metal conductors small. Energy is also lost if the energy of the photon is higher than what the solar cell can accept.
