Tomorrow today the science show on d w. Last. How do solar cells actually was so hisself are mainly composed of silicon. Silicon atoms have full electrons in the outer shell and are stable but then the silicone is split into 2 layers. Bosphorus is mixed into one layer it has 5 electrons in its outer shell one too many which can orbit free. The 2nd layer is mixed with boron which has only 3 out electrons one to feel. That means the layer has gaps which attract the excess phosphorus electrons this...

Layer is mixed with boron which has only 3 out electrons one to feel. That means the layer has gaps which attract the excess phosphorus electrons this creates a flow of negatively charged electrons from one layer to the other one layer loses electrons and becomes positive the other gains electrons and becomes negative creating 2 poles eventually all the gaps on the surface of the layers are occupied the whole and the electrons are now too far apart to migrate dance with the sun comes in when som...
