The boron emitters are formed in a co-diffusion step using boron doped PECVD layers. It is demonstrated that the formation of Ag/Al spikes results in strong FF and V<sub>OC</sub> losses limiting the solar cell efficiency. This can mainly be attributed to an increased saturation current density of the second diode which is strongly increasing with increasing set peak firing temperature. A detailed scanning electron microscopy analysis reveals that this j<sub>02</sub> increase can be attributed to an increasing area density and depth of the Ag/Al spikes for increasing peak firing temperatures.
