Dr. Michael saag. It is the at the university of alabama Birmingham School of medicine. Thank you for being here doctor period. Dr. Michael saag thank you for having me. Host is look at the reopening that is happening in many states across the country. What are you looking for as possible potential early indications of the spikes and states reopen, as that summer in singles and fall begins. Dr. Michael saag will he think that we are all concerned about, is this expansion of cases that happens over time. If we opened up too soon, then it will be an increase in cases that we will see and they wi...

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....

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 ...

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...
