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 creates a flow of negatively charged electrons from one layer to the other one layer loses in. Trans and becomes positive the other gains electrons and becomes negative create 2 poles eventually all the gaps on the surface of the law is occupied the whole and the electrons are now too far apart to migrate that is where the sun comes in when some light hits the surface layer images splits on one electron making a hole under so close election.

Cells in the panel. Welcome to tomorrow today the science show on the d. W. Stuff how do solar cells actually was so hisself are mainly composed of silicon. Silicon atoms have full electrons in their outer shell and are stable but then the city come a split into 2 layers. Last christmas mixed into one like 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 outer 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 with the sun comes in when some light hits the surface layer splits off one electron making a hold on to so close electron.

Welcome to tomorrow today the science show on the d. W. Stuff how do solar cells actually was so missiles are mainly composed of silicone. Silicon asms have full electrons in their outer shell and unstable but then the cynical misplaced into 2 layers. Los reyes is mixed into one leg it has 5 electrons in its outer shell one too many which can orbit for. The 2nd layer is mixed with go wrong 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 leg to the other one layer loses in. Trans and becomes positive the other gains electrons and becomes negative creating 2. Eventually all the gaps on the surface of the layers are 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 layer splits off one electron making a hole under so close election. The electron is attracted to the positive and t
Stuff how do solar cells actually was so hisself are mainly composed of silicone. Silicon atoms 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 5 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 poles eventually all the gaps on the surface of the layers. Occupied the whole and the electrons are now to flora plant to migrate thats where the sun comes in when some light hits the surface layer he splits off one unit making a hole under so close election. The electron is attracted to the positive and the home goes another electron from another down to re
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 some light hits the surface layer energy splits off one electron making a hole under so close electron. The electron is attracted to the positive and the home goes another electron from lower down to replace the one lost which in turn is split off and so on. The electrons which have arrived at the positive pole returned via one. To the negative. And it flows as long as the sun shines. If solar energy is to enable commercial aviation and satisfy our electricity needs in the future and theres still a
