What is difference between n-type and p-type?

The basic difference between P-type and N-type semiconductors is that in an n-type semiconductor there is an excess of negatively charged carriers. In a p-type semiconductor, there is an excess of positively charged carriers (holes, which can be thought of as the absence of an electron).

Which is best n-type or p-type?

Impurities based on the number of valence electrons can be n-type (5) or p-type (3). n-type tendencies are a better choice due to reducing LID (Light Induced Degradation) and increasing durability and performance compared to p-type.
