Stuff how do solar cells actually was so hisself are mainly composed of silicone. Silicon asms have full electrons in the outer shell and are stable but then the silicon is split into 2 layers. Bosphorus is mixed into one like it has value electrons in its outer shell one too many which can orbit for. 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 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 holes eventually all the gaps on the surface of the lay. Is occupied the holes and the electrons are now too far apart to migrate them with the sun comes in when some light hits the surface like energy splits off one electron making a hole under so close election. The electron is attracted to the positive and the hole goes another electron from another dow
To tomorrow today the science show on d w. Last. Stop how do solar cells actually but so hisself are mainly composed of silicon. Silicon atoms have full electrons in the outer shell and are stable but then the silicon misplaced into 2 layers. Bosphorus is mixed into one like it has 5 electrons in its outer shell one too many which can orbit freeney. 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 creates a flow of negatively charged electrons from one line to the other one layer loose. As electrons and becomes positive the other gains electrons and becomes negative create 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 with the sun comes in when some light hits the surface layer energy splits off one electron making a hold on to so close electron. The electron is attracted to the positive an
Unknown for you know norm which of us had. No let newfie ship of dung and one of her but not enough the took one of her fishy for so long and.
