Extrinsic semiconductors are divided into n-type semiconductors and p-type semiconductors according to the type of impurities ...

Semiconductors are sometimes considered to be insulators with narrow band gaps. For a visual explanation of N-type versus P-type semiconductors, including a clear visual explanation of the band ...

A 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 ...
