The continual increase in cell efficiency of passivated emitter and rear cells (PERCs), as well as the optimization of the module processes, has led to significant advances in module power and efficiency. To achieve the
highest module power output, one important aspect to consider is the optimization of the solar cell front metallization and the cell interconnection.
