A solar cell may include a PN junction including a semiconductor substrate of a first conductivity and an emitter of a second conductivity, a passivation layer on an exposed surface of the semiconductor substrate, a first electrode connected to the semiconductor substrate, and a second electrode connected to the emitter. The passivation layer may be configured to apply stress to the exposed surface of the substrate such that a mobility of minority charge carriers in the semiconductor substrate is decreased in a first direction perpendicular to a boundary surface of the semiconductor substrate and the passivation layer.
