StroKoFo – Current Assisted Contact Formation of Metal-Semiconductor Contacts
Performance data of two groups of solar cells with passivated emitter and rear: in blue the best group without StroKoFo treatment, in red the best group of the experiment with StroKoFo process, which increases the efficiency of the solar cells significantly, by 0.37%abs.
The StroKoFo project focuses on an innovative process for forming or optimizing the metal-semiconductor contact of silicon solar cells (StroKoFo process), which is based on a different physical principle than the conventional firing process.
The use of this process creates new degrees of freedom in the choice of metal pastes, emitter layers, passivation layers and finger geometry. These additional degrees of freedom have great potential to increase the efficiency for various solar cell manufacturing concepts. The goal of the project is to raise the StroKoFo process from its previous technology readiness level (TRL) 4 to TRL 8. For this purpose, the StroKoFo process will be integrated into the pilot production of Fraunhofer ISE in order to investigate the influence of the StroKoFo process on highly efficient PERC and TOPCon solar cells with specifically varied properties and thus to prove the efficiency increase potential of the StroKoFo process for these cell concepts. A StroKoFo-related efficiency increase of up to 0.5 % abs. is assumed.
