Therefore, DFT calculations in gas phase as well as in the implicit solvent model (solvent = DMF) yield consistent results, that HFB reacts with FAI to form [FAI⋯HFB] and retards the reaction between FAI and PbI2. Extended Data Fig. 3 Anion–π interaction between the AX component...
The improved stability is probably originated from two reasons: (1) the smaller radii of Cs and Rb cations in MA/FA perovskites can suppress a phasetransition from black to yellow during the operation of solar cell; (2) ion migration may be suppressed in the triple-cation perovskite systems....
TSynpSi4c/aSlely4 (M = Zn, Mn it may lead to and Fe) helps in tuning an improvement in the the optoelectronic properties band gap energy from 1.0 eV to 1.5 eV and also suppress the formation of the secondary phase19. To date, there are only a few reports on the ...
been shown to suppress Pt activity mainly due to competitive adsorption effects28. For the OER, previous experiments on Pt in HClO4(~pH 0.1) and H2SO4(~pH 0.3) suggest differences in activity and Tafel slope between the two electrolyte compositions and pH’s23. For the HOR, the suggested ...
