N-type semiconductors have a larger electron concentration than hole concentration.
The phrase ‘n-type’ comes from the negative charge of the electron. In N-type semiconductor, electrons are the majority carriers and holes are the minority carriers. A common dopant for n-type silicon is phosphorus.
Typically, it is said that n-type solar cells have higher efficiencies (and thus higher output per unit area) than p-type solar cells.
