Zn(II) and Cu(II) tetrakis(diarylamine)phthalocyanines as hole-transporting materials for perovskite solar cells

Mohammad Khaja Nazeeruddin, Kasparas Rakstys, Hiroyuki Kanda, Cansu Igci, Nadja Isabelle Desiree Klipfel, Maria Cristina Momblona Rincón, Jianxing Xia

Finding new hole-transporting materials (HTMs) suitable for replacing the state-of-the-art spiro-OMe-TAD is still challenging. In this work, newly synthesized diarylamine-substituted metal phthalocyanines (MPcs, M 1/4 Zn(II) or Cu(II)) functionalized with ...

Dion-Jacobson and Ruddlesden-Popper double-phase 2D perovskites for solar cells

Bowen Yang

Dion-Jacobson (DJ) phase and Ruddlesden-Popper phase 2D perovskites have been, individually, demonstrated to be more stable than 3D counterparts for perovskite solar cells (PSCs). In order to further improve the efficiency and stability of 2D PSCs, we here ...
