3. Solar Energy- Photovoltaic cells How do they work? ▫ Photovoltaic cells should convert sunlight to electricity. ▫ For that we need  Sunlight  Some material that can generate electrons when light is incident on it. Silicon is used for its properties to generate electrons easily! All electronics also use Silicon. 3

4. Solar cell Has two electrodes, positive and a negative(similar to a battery) The energy of the sunlight(photon) removes electrons from Silicon and cause electricity. 4

6. LED-Light Emitting Diode Connect a LED to one solar cell and see if it glows. Connect two solar cells in series and see if the LED glows. Connect three solar cells in series and see if the LED glows. Four solar cells? What made the LED glow? 6
