Abstract:
Interdigitated Back Contact (IBC) cells have been fabricated at ECN laboratories with a best cell efficiency of 19.1%, using n-type Cz material and a process flow based on all-screen-printed patterning and metallization. Excellent current collection due to an optimized FSF is demonstrated by a Jsc value as high as 41.5 mA/cm2, corrected for spectral mismatch, and a Voc of 641 mV. The results show high Pseudo Fill Factors (PFF) of above 81% but lower Fill Factors (FF) of below 72%.
