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
Ted koppel will remind us in our cover story. I talk about the chinese virus. You might think that the Chinese Government chinas coverup. Has had enough of President Trump. Think again. There is actually some people who are saying mr. Trump is a godsend to china because he is helping to destroy the image of the United States. The actions and rhetoric from the american president have been distressing. What is undeniable is that President Trump has changed th what is undeniable is that the President Trump has changed the image of the United States, for better, for worse . Well hear from friends and adversaries around the world, coming up on sunday morning. Pauley day after day, despite the coronavirus shutdown, broadway theaters are keeping their lights on, this sunday in particular. As mo rocca will show us. On what would have been ton on what would have been tony sunday, broadway is quiet. The seats empty, but every stage on the great white way is still illuminated by something called
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
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
How do solar cells actually was surface else are mainly composed of silicone. Silicon asms have full electrons in their outer shell and are stable but then the silicone 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. Is occupied the holes and the electrons are now to florida plant to migrate them with the sun comes in when some light hits the surface layer splits on one electron making a hold on to supply selection. The electron is attracted to the positive and the hole goes another electron from lower down to replace the one
