    Low temperature interconnection techniques for high efficiency heterojunction solar cells

    No full text
    The heterojunction cell concept enables high efficiencies and simultaneously low-cost production. Roth & Rau AG provide tools and processes for mass production of heterojunction technology (HJT) based solar cells. New low temperature interconnection techniques are needed for this cell concept. This work focuses on the evaluation of the characteristics of polymer pastes based on silver and copper particles. Therefore different curing atmospheres of an inert inline drying system (Rehm Thermal Systems) were used. The electrical resistance, adhesion, and solderability of the screen printed pastes were evaluated. As we will show in the present work, the currently available copper pastes can be an equivalent alternative to common used silver pastes
