6 FAQs about [Design of silicon back surface field of solar cell]
What is a back surface field in a solar cell?
A "back surface field" (BSF) consists of a higher doped region at the rear surface of the solar cell. The interface between the high and low doped region behaves like a p-n junction. An electric field forms at the interface, which introduces a barrier to minority carrier flow to the rear surface.

How does a BSF increase a solar cell's voltage?
A BSF increases the voltage of a solar cell. An extra heavy doping at the rear establishes a field that keeps minority carriers (in this case, electrons) from the highly recombining rear surface. The reduction in recombination increases the electron concentration in the base and so the solar cell's voltage.
