Black silicon is made when the surface of regular silicon is etched to produce tiny nanoscale pits on the surface. In order to charge the layers positively and negatively, additional elements are simply added. An integrated phosphorus atom creates a negatively charged silicon layer, while a boron atom creates a. . Researchers at the U. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have developed a new theoretical model explaining one way to make black silicon, an important material used in solar cells, light sensors, antibacterial surfaces and many other applications. Silicon is also used in virtually every modern electronic device, including the one you're reading this on. Unless you printed it out. The. . The dark-colored panels you see on the roof of your house are composed of solar cells. More than 90% of solar modules today. .
