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
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
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
Fun. Look at this. The president living it up in motown last hour calling on republicans to stop being party poopers. I believe america only succeeds and thrives when weve got a strong and growing middle class. I want us to bring down our deficits but i want to do it in a balanced, responsible way. And i want to reward i want a tax code that rewards businesses and manufacturers, like Detroit Diesel right here creating jobs right here in redford, right here in michigan. Right here in the United States of america. Rhetoric like that might be working. Look at the headline today. End game approaching as its looking more and more likely that the republicans forced to give in on taxes. House Speaker John Boehner after a secret white house meeting this weekend says the lines of communication between both sides remain open. But what would the gop demand for a concession on taxes and how much leverage do they have left . Lets bring back dr. Jay john allen for politico. How are you, sir . Doing
