We show that a microscopic definition of crystal defect, based on the effective mean singleparticle potential energy, makes it possible to detect and visualize various types of local and extended crystal defects and develop an effective algorithm for tracking their time evolution.

Large defect clusters can represent a serious reduction of the material quality of multicrystalline silicon and the efficiency of the resulting solar cells. It is useful to find the origin of these defect rich regions in order to understand their formations. For this work, multicrystalline silicon wafers from different positions of a compensated p type silicon brick were processed to solar cell...
