back-surface field

back-surface field

[′bak ‚sər·fəs ‚fēld]
(electronics)
A p +layer that is added to a silicon solar cell to reduce electron-hole recombination at the cell's back surface and thereby increase the cell's efficiency.

Furthermore, the potential benefit of the Ga content increases from notch towards the back contact induces a back-surface field in the conduction band, which causes electrons to drift away from the rear contact and thereby reduces the recombination at the back contact [8].
