Boron conductor
WebA solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms ... WebThe count of these elements like antimony, phosphorus or arsenic donates free electrons so that the intrinsic semiconductor conductivity will be increased greatly. For instance, once a Si crystal is doped with a Group …
