The higher the resistivity of silicon wafers, the better?!!! 1 experts please answer me!
The resistivity is as narrow as possible, high resistance and low resistance can have high efficiency, is stable, easy to make a smooth PN junction in the diffusion resistance, high in the junction zone will less less complex, but more difficult to do the PN junction intact, low resistance lifetime will be shorter, but the PN junction will do very smooth, the higher resistivity is not the main, mainly has the corresponding process to match, want to have a stable process with stable resistivity.
Low resistivity is helpful to improve the opening pressure, high resistivity and help to improve the short-circuit current, the best match between the two is about 1 -3! Own understanding!
Weak questions: why single crystal resistivity in about 1 would be better?
