The perovskite solution
was prepared by mixing the precursors PbI₂ (TCI Chemicals),
PbBr₂ (TCI Chemicals), CH(NH₂)₂I
(FAI, GreatCell Solar), CH₃NH₃Br (MABr, GreatCell
Solar), and CsI (Alfa Aesar) in a 3:1 (vol %) N,N-dimethylformamide (DMF, anhydrous, Sigma-Aldrich):dimethyl
sulfoxide (DMSO, anhydrous, Sigma-Aldrich) ratio with a concentration
of 0.8 M. The precursors were added with the following ratios: Cs_0.1(MA_0.17FA_0.83)_0.9Pb_0.84(I_0.8Br_0.2)_2.68. The resulting
film thickness of the triple cation perovskite is ca. 220 nm. The
perovskite films were deposited on the glass substrates by a two-step
spin-coating process: In the first step, the perovskite solution was
spin-coated dynamically at 1000 rpm for 10 s. In the second step,
at 6000 rpm, for 20 s, chlorobenzene (anhydrous, Sigma-Aldrich, 100
μL) was dripped onto the sample after 12 s. The films were annealed
at 100 °C for 1 h to complete the crystallization process. The
complete process is performed in a nitrogen-filled glovebox.

Deuteration of Formamidinium Iodide

CH(NH₂)₂I (FAI, Greatcell Solar Materials Pty Ltd.) was dissolved in excessive D oxide (Sigma-Aldrich, 99.9 atom %) at a molar ratio of 1:40 under stirring, followed by heating the solution to 90°C for 2 h under argon (Ar). The liquid was then evaporated at 70°C under a flow of Ar to dry off. This process was repeated three times to ensure complete substitution of ammonium H by D to yield the high purity of D–FAI. Finally, the white solid was collected and moved to the vacuum oven at 60°C overnight for further drying. In principle, most of the D₂O can be recollected by reflux for future scaled-up synthesis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
