Crystalline silicon solar cells – the magic of physics that converts light to electricity

You all would have seen photovoltaic panels on buildings on in a garden. All they need is sunlight and these panels can light the bulbs, run fans, radio, television and recharge your phones. Have you ever wondered how do these panels generate electricity ? What makes them so special and different from other sources of electricity ?

Most photovoltaic panels have silicon solar cells which are the blue or black rectangles within the panels that convert light to electricity thanks to physics and some creative engineers. You can find out more about the magic and physics of converting light to electricity in this interesting lecture. Then next time you see these panels while driving with your family or friends, you can explain them how these panels work.
