For high efficiency solar cell concepts there is a need for separate treatments to the front and rear side of a silicon wafer [1]. A smooth polished rear surface is desirable for passivated cell concepts (e.g. PERC) as the flat surface decreases the surface recombination velocity and leads to an increase in light trapping [2].
