Efficient and stable solid-state light-emitting electrochemical cell using tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II) hexafluorophosphate.
TL;DR: The complex tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II), prepared via a simple microwave-assisted synthesis, was used to prepare a single-layer light-emitting electrochemical cell that reaches a high power efficiency and lifetime.
Journal ArticleDOI
Large-Grain Tin-Rich Perovskite Films for Efficient Solar Cells via Metal Alloying Technique
Mohammad Mahdi Tavakoli,Mohammad Mahdi Tavakoli,Shaik M. Zakeeruddin,Michael Grätzel,Zhiyong Fan +4 more
TL;DR: A novel and facile technique is presented to fabricate tin (Sn)-rich perovskite film using metal precursors and an alloying technique that can open up a new direction to further explore different alloy systems (binary or ternary alloys) with even lower melting point.
Journal ArticleDOI
Stabilization of the Perovskite Phase of Formamidinium Lead Triiodide by Methylammonium, Cs, and/or Rb Doping
TL;DR: Cs+ and Rb+ are shown to be more efficient in the stabilization of the perovskite α phase than MA+.
Journal ArticleDOI

Fei Zhang,Fei Zhang,Shirong Wang,Hongwei Zhu,Xicheng Liu,Hongli Liu,Xianggao Li,Yin Xiao,Shaik M. Zakeeruddin,Michael Grätzel +9 more
TL;DR: In this article, three hole-transporting materials (HTMs) based on the phenothiazine core containing 4,4-dimethyltriphenylamine (Z28), N-ethylcarbazole (Z29), and 4, 4-dimethoxytriphenylonitriou tetramethylpolysilicon (Z30) as the peripheral groups connected by double bonds were designed and synthesized.
Journal ArticleDOI
Substituent Effect on the Meso-Substituted Porphyrins: Theoretical Screening of Sensitizer Candidates for Dye-Sensitized Solar Cells
TL;DR: The results show that the candidates selected are very promising to provide good performances as sensitizers, in which ZnTPPG is promising to challenge the current photo-electric conversion efficiency record 7.1% of porphyrin-sensitized solar cells.
