TL;DR: In this paper, the pseudo-halide anion formate (HCOO−) was used to suppress anion-vacancy defects that are present at grain boundaries and at the surface of the perovskite films.
Journal ArticleDOI
Dynamic nuclear polarization surface enhanced NMR spectroscopy.
Aaron J. Rossini,Alexandre Zagdoun,Moreno Lelli,Anne Lesage,Christophe Copéret,Lyndon Emsley +5 more
TL;DR: The successful application of DNP SENS to characterize hybrid materials, organometallic surface species, and metal-organic frameworks is described, which enables the detailed and expedient atomic level characterization of the surfaces of complex materials at natural isotopic abundance and opens new avenues for NMR.
Journal ArticleDOI

TL;DR: In this paper, it was shown that surface NMR spectra can be greatly enhanced using dynamic nuclear polarization, which transferred from the protons of the solvent to the rare nuclei at the surface, yielding at least a 50-fold signal enhancement for surface species covalently incorporated into a silica framework.
Journal ArticleDOI
Vapor-assisted deposition of highly efficient, stable black-phase FAPbI3 perovskite solar cells.
Haizhou Lu,Yuhang Liu,Paramvir Ahlawat,Aditya Mishra,Wolfgang Tress,Felix Eickemeyer,Yingguo Yang,Fan Fu,Zaiwei Wang,Claudia E. Avalos,Brian Carlsen,Anand Agarwalla,Xin Zhang,Xiaoguo Li,Yiqiang Zhan,Shaik M. Zakeeruddin,Lyndon Emsley,Ursula Rothlisberger,Li-Rong Zheng,Anders Hagfeldt,Michael Grätzel +20 more
TL;DR: A deposition method using methylammonium thiocyanate vapor treatment to convert δ-FAPbI3 to the desired pure α-phase below the thermodynamic phase-transition temperature is shown.
Journal ArticleDOI
Through-Bond Carbon−Carbon Connectivities in Disordered Solids by NMR
TL;DR: In this paper, a refocused INADEQUATE NMR experiment is used to obtain homonuclear carbon−carbon through-bond correlations in disordered organic solids where the line widths greatly exceed the value of the scalar coupling.
