Abstract
Direct casting of silicon into wafers allows to produce wafers much more cheaply than in traditional block casting methods. RGS (ribbon growth on substrate) is such a method. In order for RGS to be cost effective sufficient cell efficiencies must be realized. In this paper we present a 12.9% efficient screen printed RGS cell. This is an increase of 0.6% absolute compared to the best previous result reported in January 2005. The increase was achieved by reducing shunting in cells made on RGS material
