Extended X-ray absorption fine structure (EXAFS) of FAPbI3 for understanding local structure-stability relation in perovskite solar cells

In Situ and Operando Characterizations of Metal Halide Perovskite and Solar Cells: Insights from Lab-Sized Devices to Upscaling Processes

“…Therefore, a close understanding of crystallization paths at the atomic level will benefit compositional and device engineering. Techniques such as EXAFS and pair distribution function (PDF) probes short-range atomic order and can help in this task itself, but combined with simulations, can go even close to atomic level transformation. ,− …”

Stability and efficiency improvement of perovskite solar cells by surface hydroxyl defect passivation of SnO2 layer with 4-fluorothiophenol

“…All the data fitting processes were conducted through ATHENA. 41 EIS measurement data were obtained from an Autolab electrochemical working station with an amplitude of 20 mV at voltage ranging from 0.0 V to 1.0 V under one sun illumination. The frequency range was 1 MHz to 850 Hz.…”

Antiseptic Povidone–Iodine Heals the Grain Boundary of Perovskite Solar Cells

“…Fluorine-doped tin oxide glass (FTO, T18VU70, 12−13 Ω/sq, AGC Fabritech Co., Ltd.) was cleaned by the method described in the literature. 55 For a thin SnO 2 electron transport layer, a diluted SnO 2 colloidal solution (15 wt %, Alfa Aesar) was spin coated according to the procedure reported elsewhere. 45 FAPbI 3 films were prepared according to the methods reported previosly, 45,55 where MACl and CsCl were included in the perovskite precursor solution (solvent was a dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) mixture), diethyl ether was used for the antisolvent dropping process, and the annealing temperature and time were 150 °C and 10 min.…”
