How does PERC work?

Definition:
PERC technology is a design improvement technology for photovoltaic cells, aiming to enhance the overall photoelectric conversion efficiency of the cells by reducing recombination losses on the back surface and improving back surface reflection.

Working Principle:

• Passivation: By adding a dielectric passivation layer (such as aluminum oxide Al2O3 or silicon nitride SiN) on the back of the cell, the recombination losses on the back surface are reduced, that is, the non-radiative recombination of photogenerated carriers on the back surface is decreased.

• Reflection: The passivation layer also has a high reflectivity, which can reflect the unabsorbed light back into the cell, increasing the absorption probability of photons and thereby enhancing the short-circuit current (Is).

• Hole-opening: Holes are opened on the passivation layer (by means of lasers, etc.) to form metal contact points for current collection.
