In recent years, some suitable solutions to produce solar cells with selective emitter have been established. One of the simplest but also most advanced methods is laser-doping of PSG (Hahn, 2010). The process will result in an increase in efficiency for mono- as well as for multi-crystalline cells (Kohler et al., 2009). A detailed analysis of industrially produced multi-crystalline silicon solar cells with selective emitter is given here. The function of these cells in the module in comparison to standard cells is shown. Advantages and disadvantages of this technology in industrial applications are investigated.
