摘要

Laser processing of wafers for solar cell production is used i.e. for the application of local laser ablation of dielectric materials for PERC solar cell processing. In the present study 3 different laser-sources and parameters were used for local-contact openings (LCO) on the rear side of the wafer with subsequent metallization. For a microstructure analysis cross-sections have been prepared and investigated by means of scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDX). We detected in addition to the rear contacts with Al/Si-phase (filled contact) formed voids (void contact) at expected filled contact positions which are caused by the Kirkendall effect. Filled and void contacts are found to be comparable in size and shape. Void contacts can be differentiated in total and intermediate void formations. Detailed measurements revealed information about local rear contact doping in according to the type of formed contact as well as microstructural details of the initial state of the void contact formation process.
