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.

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

Apple warning that coronavirus will hit revenues. The drop in apple surprisingly small. Flat as investors see little new in this reboot. We are going to get 35,000 job cuts, though. And franklin buying legg mason. L scale project s of protect active Asset Managers from the storm ripping through this industry . From london, im guy johnson, with vonnie quinn in new york. We are counting you down to the european close on bloomberg markets. Vonnie grinding lower, but slowly. We are down zero. 4 on the s p 500 as more and more companies talked about the impact of the coronavirus shortterm and more intermediateterm on their businesses, including the apple, and of course which is what spooked the markets after a possible turnaround day yesterday. Apple said it would tried to china said it would try to shore up its economy. We are also getting some good earnings reports helping shore up some of the market. Gold futures above 1600 an ounce, and that is all just in the last few minutes. It does
500 infotech index up 48 , and the energy index was the least best performer. It still was up, though, which tells you how much these markets were looking for good news. The second best performer, Consumer Discretionary in the s p 500. That includes home depot to amazon, ebay, even general motors, so really across the board, it was a good year. For more on the markets more broadly, we are joined by ing head ofvey, global debt and rate strategy. We widened the curve with a bit of steepening going on. To what do you attribute that . Been a really interesting move. We were inverted six months ago. Happened is the fed has cut 75 basis points. Theyve injected a mountain of liquidity into the system, and theres been a real change in sentiment in the sense that six months ago, we were genuinely concerned about a recession in the u. S. Next year. Have beenerns significantly downsized. Theres still trimming this uncertainty, and we so have a very flat curve. If you look at the twostens, it is n
