TL;DR: The novel HTM containing six units of oligotriarylamine (HAB1), characterized by UV-vis, cyclic voltammetry, DFT, and thermogravimetric analysis, confirms its suitability as an efficient HTM in PSCs.
Journal ArticleDOI
Steric hindrance at metal centre quenches green phosphorescence of cationic iridium(III) complexes with 1-(2-pyridyl)-pyrazoles
TL;DR: In this paper, a cyclometalating-ligand-centered excited state with structured emission spectrum and with quantum yield and excited-state lifetime of up to 26% and 1.4 mu s in argon-saturated dichloromethane solution.
Journal ArticleDOI
Multistep Photoluminescence Decay Reveals Dissociation of Geminate Charge Pairs in Organolead Trihalide Perovskites
Ramūnas Augulis,Marius Franckevičius,Vytautas Abramavicius,Darius Abramavicius,Shaik M. Zakeeruddin,Michael Grätzel,Vidmantas Gulbinas +6 more
TL;DR: In this article, the authors analyzed the charge carrier dynamics in organolead iodide perovskites by employing time-resolved photoluminescence spectroscopy with several ps time resolution.
Journal ArticleDOI
Panchromatic light harvesting by dye- and quantum dot-sensitized solar cells
TL;DR: In this paper, a PbS:Hg quantum dots-sensitized solar cell (QDSC) combined with a dye-sensor solar cell was used to harvest panchromatic solar spectrum from the visible light to the near IR.
Journal ArticleDOI
Crystal structure of tris(4,4'-dimethoxy-2,2'-bipyridine)iron(ii) bis(hexafluorophosphate), solvate with n-methyl-2-pyrrolidone
TL;DR: The trication of tris(4,4′-dimethoxy-2,2′-bipyridine)iron(II)bis(hexafluorophosphate) (crystal solvate with N -methyl-2-pyrrolidone) was performed at 295 K.
