P-n junction terminal voltage constitute a certain potential barrier, when the positive bias voltage drop time base, P and N the majority carrier diffusion to the other party.Due to the electron mobility is much bigger than hole mobility, so there will be a large number of electronic spreading P area, constitute of P area of minority carrier injection.These electrons and valence with hole composite, composite when the energy in the form of light energy to release out.This is the principle of PN junction glow.
