'''Low level injection''' conditions for a [[P-N junction]] refers to the state where the number of carriers generated are small compared to the [[background doping density]] of the material. Essentially, the semiconductor's majority carrier concentration will remain (relatively) unchanged, while the minority carrier concentration sees a large increase. In this condition [[Carrier generation and recombination|minority carrier recombination]] rates are linear.<ref>Jenny Nelson, The Physics of Solar Cells, Imperial College Press, UK, 2007 pp. 266-267</ref>

The following equation must be satisfied for a semiconductor under carrier injection conditions, where n is the number of electrons, delta N is the excess carriers injected into the semiconductor and n0 is the equilibrium concentration of electrons in the semiconductor:
:<math> n=\Delta n+n_0</math>
The following relation must also be true, because for every electron injected a hole must also be created to keep a balance of charge:
:<math> \Delta n=\Delta p </math>

The assumption of low level injection can be made regarding an n-type semiconductor, which affects the equations in the following way:
:<math> \Delta n<<N_D </math>
: Therefore <math> n=N_D </math> and <math>p=\Delta p+p_0</math>.

In comparison a [[semiconductor]] in [[high injection]] means that the number of generated [[Charge carrier|carrier]]s is large compared to the background doping density of the material. In this condition minority carrier recombination rates are proportional to the number of carriers squared<ref>R. R. King, R. A. Sinton, and R. M.
