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 …

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 …

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 …

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 …

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 …

2022年7月28日 · We propose stabilization of the perovskite by converting excess PbI 2 into an inactive, new, secondary-phase (PbI 2) 2 RbCl that can improve the stability of the perovskite …

Introducing a stoichiometric excess of lead iodide (PbI 2) in perovskite films has been demonstrated as an effective passivation strategy that can improve the power conversion …

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 …

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 …
