The single crystal PbI2 is characterized using: XRD: single crystal and powder X-ray diffraction (D8 Venture Bruker and D8 Advance Bruker) EDX: Energy-dispersive X-ray spectroscopy for stoichiometric analysis

2022年11月13日 · The PbI 2-DMSO-assisted MAPbI 3 wafer shows higher XRD intensity for the (110) and (220) peaks than the conventional wafer suggesting better crystallinity in line with the SEM images. The steady-state photoluminescence (PL) and time-resolved photoluminescence (TRPL) properties of the conventional and PbI 2 -DMSO assisted MAPbI 3 perovskite ...

Morphology of perovskite film is a key important for achieving high performance perovskite solar cells. Perovskite films are commonly prepared by two-step spin-coating method. However, pin-holes...

The examination of phase, crystallinity, morphology, and opto-electronic properties of the well-structured nanocone arrays is characterized by X-ray diffraction (XRD), scanning electron...

2022年7月28日 · The XRD and SEM results showed that more PbI 2 was formed after heating of the control perovskite film (figs. S5 and S6). We found that integration of the XRD intensity ratio of PbI 2 /perovskite in the control film increased from 0.42 to 0.98

In this work, we use a combination of dispersion-corrected density functional theory (DFT-D3) and the TiberCAD framework for the first time to investigate a newly designed and synthesized class of...

2025年1月1日 · X-ray diffraction (XRD) was utilized to investigate the effects of RbCl and VB4 on the structural properties of PbI 2. As depicted in Fig. 1 e, the addition of RbCl alone does not significantly alter the structure of PbI 2 .

相关xrd图谱(图1diii)旋涂膜显示pbi2•nmp和pbx2•nmp/dmf复合物存在，而不含fa2pb3i8•4dmf。 XRD图谱(图5)表明沉积过程中相对较低的前驱体溶液挥发率(自旋速率>3000 rpm)足以实现致密的钙钛矿薄膜，即使没有反溶剂过程。

2016年9月1日 · XRD and NMR patterns indicate the superoxide generation through electron transfer from MAPbI 3 * to O 2 which attacks the perovskite absorber leading to the formation of methylamine (MeNH 2), lead iodide, iodine, and water as degradation products.

Both UV-vis absorption spectrum and XRD spectrum proved the existence of PbI 2 (DMSO) domains, which decreased the devices EQE over 300–450 nm. Finally, by increasing the ratio of MAI in...
