surface recombination velocity

surface recombination velocity

[′sər·fəs rē‚käm·bə′nā·shən və‚läs·əd·ē]
(solid-state physics)
A measure of the rate of recombination between electrons and holes at the surface of a semiconductor, equal to the component of the electron or hole current density normal to the surface divided by the excess electron or hole volume charge density close to the surface.

The modeling of photovoltaic devices is not simple; it depends heavily on several intrinsic optoelectronic properties of the material, such as surface recombination velocity and volume, lifetime of minority carriers, and the doping level which is one of the extrinsic parameters which play an essential role.
n] is the back surface recombination velocity of electrons and w is the space charge width.
