How Solar Panels Work
The main work of solar panels is to convert energy gotten from the sun into electrical energy. For this to be possible, solar panels are made from special semiconductors. These conductors are made from silicon atoms. This is because silicon helps to get the needed photons.
The process involved here is that loose electrons will be knocked off once the sun’s photons strike silicon atoms. This will then create an electronic field with the movements of the electrons. There is usually a wire in the N-layer that directs all the free electrons into their respective areas. Those electrons with energy otherwise known as electric current will continue flowing to produce the desired results as long as the sun shines.
This process will continue rotating like this as long as the sun is up. The electrons will move from the N-layer and back to the P-layer as long as the sun shines. It is similar to a water cycle.
