Electrical effects of SiC inclusions in EFG silicon ribbon solar cells

Abstract
The electrical effects of included silicon carbide (SiC) particles in edge‐defined film‐fed grown silicon ribbons have been examined. By employing a scanning electron microscope operated in the electron‐beam‐induced current mode, as well as observing the effects of SiC particles on solar‐cell characteristics, the electrical activity of particles and particle‐generated defects were studied. The influence of SiC particles largely appears to be a result of impurity accumulation around them rather than a direct effect of the inclusions.
