$SolarSurfaceRM

$SolarSurfaceRM is the command for user to consider the surface recombination. Usually in 1D simulation, it is hard to consider the air/semiconductor surface state recombination. Therefore, user will need to consider an effective surface recombination velocity in the simulation to account for the surface recombination.

The format is

$SolarSurfaceRM
Electron_SurfaceRM(cm/s)  hole_SurfaceRM(cm/s)
index_left_contact  index_right_contact

Electron_SurfaceRM is the electron surface recombination velocity.
hole_SurfaceRM is the hole surface recombination velocity.
The way to obtain the velocity is
$R=S{e}_{RM}(n-n_i)$
$R=S{h}_{RM}(p-p_i)$

$S{e}_{RM}$ is the Electron Surface recombination
$S{h}_{RM}$ is the hole Surface recombination

index_left_contact= 1  : electrons recombine at the left surface 
 
index_left_contact= 2 :  holes recombine at the left surface 
 
index_right_contact= 1  : electrons recombine at the right surface 
 
index_riggh_contact= 2 :  holes recombine at the right surface
