  • Descrição: Hexaazatrinaphthylene (HATNA) derivatives have been successfully shown to function as efficient electron‐transporting materials (ETMs) for perovskite solar cells (PVSCs). The cells demonstrate a superior power conversion efficiency (PCE) of 17.6 % with negligible hysteresis. This study provides one of the first nonfullerene small‐molecule‐based ETMs for high‐performance p–i–n PVSCs. Glück und Schwefel: Energieniveaus und Verarbeitungsfähigkeit in Lösung von Hexaazatrinaphthylen(HATNA)‐Derivaten lassen sich durch Einführung verschieden langer Alkylsulfanyl‐Seitenketten mit Schwefel in unterschiedlichen Oxidationsstufen genau einstellen. Perowskit‐Solarzellen mit diesen HATNA‐Derivaten als Elektronentransportmaterialien erreichten Wirkungsgrade bis 17.6 %.
