Tv as the final numbers came in over the weekend but of course is a long certification process and appeals like yes by President Trump going in the meantime weve got lots of news to get to this morning. Im darya folsom and im james what you can see by the shot behind us the live pictures from the base obviously very clear out there its getting brighter but that clear sky but a pattern john means what cold temperatures for a lot of folks this morning though yeah frigid start guys it sure does look beautiful out there though, but as you are stepping outside dont be fooled by the sunshine were off to a very cool kick this morning that a way to write up as she get out there at least theres the plus to it you can see that we do have frost advisories in effect across the bay area this morning most notably across the north bay so in purple, those are freeze warnings in northern solano and then also in lake county in the lighter blue and portions of marine sonoma and napa counties. Frost advis
Election descended into name calling and interruptions the 2nd round however is now in downtown with donald trump contract coronavirus. Joining us 1 pm here in the russian capital this is the weekly. Theres been a week of deadly hostilities between armenia and azerbaijan in the disputed nagornokarabakh region strikes have destroyed multiple buildings with conflicting reports on casualties late on saturday to the explosions were heard in the disputed regions capital. Have been heard throughout sunday morning with more damage inflicted across the city on friday a Field Hospital was hit in a bombing raid several residential buildings were also badly damaged and reports just just the leader of the selfproclaimed the going to care about republic was badly injured on sunday. Also this week a steady spill beyond the confines of the disputed territory when a bordering azeri town was bombed by john claims that more than 2000 shells were dropped in that raid also says since the start of fighting
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
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.
