Split-Standing Molecular Engineering for Textured Silicon/Perovskite Tandems.

ABSTRACT: To effectively minimize reflection losses and achieve compatibility with industrial-scale silicon production lines, textured silicon/perovskite tandem solar cells have garnered significant attention in recent research. However, achieving uniform and stable coverage of the textured silicon substrate with hole-selective layer (HSL) remains a significant challenge. Herein, a HSL material, DPAICz ((indolo[2,3-a]carbazole-11,12-diylbis(ethane-2,1-diyl))bis(phosphonic acid)), is reported specifically designed for textured silicon substrate. Compared to the typical HSL material 2PACz, DPAICz features a π-expanded conjugated core and multiple anchoring groups, forming a split-standing configuration with anchoring groups positioned on opposite sides, resulting in superior anchoring stability on tex
