Abstract :
We present small-area metal wrap through solar cells with passivated rear side (MWT-PERC), screen-printed metallization, and a homogeneous industrial-like emitter showing an efficiency of 20.2%. A comparison of H-pattern reference cells and cells with aluminum back surface field confirms the advantages of the MWT-PERC approach and reveals significant synergistic effects of rear-surface passivation and wrap through metallization.
