Solar Systems are capital intensive goods that will operate over a long period of time. In order to
positively impact lifetime quality requirements, intensified process- and quality control is desirable. Laser marking is
providing a meaningful contribution to these requirements. Applied to raw wafer at the beginning of the
manufacturing process, each solar cell becomes traceable along the entire value chain and over the whole lifetime –
since laser marking is a hard physical coding. As usual it takes transition work from patented innovation at laboratory
stage till mass production proof. At Q-Cells we have gained vast experience by marking great number of solar cells
under mass production conditions. The paper highlights some of the key factors to be considered for high yielding inline
laser marking of silicon solar cells, since interest of customers and suppliers is rising for this topic in the
industry.
