“…This makes it potentially interesting for a large range of applications such as the analysis of thin photovoltaic films, LED, hard disks, electrodes for Li batteries, coated glasses, or for surface treat ments and advanced coatings to improve performance or corro sion resistance. [37][38][39][40][41] Most of the few papers reporting on the use of GDOES for PSCs investigation are limited to the basic analysis of PSC structure. [42][43][44][45][46][47][48] In recent years, GDOES has also been applied by Geffroy et al [49,50] and by our group [22] to directly study the ion migration during cell operation.…”

The emerging broad range of applications of the glow discharge optical emission spectroscopy (GD‐OES) technique in the field of perovskite solar cells (PSCs) research is reviewed. It can provide a large palette of information by easily and quickly tracking the depth distribution of light to heavy elements. After a discussion of the advantages and the limitations of the technique and a comparison with other analytical techniques, how GD‐OES is employed to give structural information on perovskite solar cells is shown. GD‐OES has allowed the full perovskite film formation process investigation, from the initial precursor layers containing soaking and complexed solvent to the final crystallized 3D perovskite layers. The A‐site elemental cations distribution is followed‐up during the film formation. In addition, this technique gives a deep insight into the action mechanism of additives and their effects on the film formation. It provides fruitful information on optimized light absorbing layers and on the selective contact layers which ensure the charge transport in PSCs. It allows to directly visualize halide ions migration and their blocking by ad‐hoc chemical engineering and to study the films and PSCs ageing. GD‐OES opens new perspectives to explain the final performances of the devices.

“…Zircon is known for its unique properties, such as high density leading to a high refractive index, high hardness along with brittleness, tenacity, durability, etc. [ 5,24 ] In crystalline form, it shows high resistance to most of the acids. Additionally, due to its actinide loading capacity, it is being researched as a potential nuclear waste storage material by synthesizing it in the laboratory.…”

Structural properties of Indian metamict single zircon crystals are studied by comparing their properties with those of synthetic zircon synthesized via solid‐state reaction method, which serves as the standard. X‐Ray diffraction (XRD) data reveal changes in lattice parameters and the presence of strain, metamictization, etc. It is found that the degree of crystallinity is ≈63.8% indicating the simultaneous presence of crystalline and disordered regions. These changes are likely due to the presence of several radioactive/nonradioactive elements. The presence of such elements is observed and the sample composition is analyzed through total reflection X‐Ray fluorescence. XRD crystallographic data are further utilized as input for analyzing X‐Ray absorption spectroscopy data recorded around Zr central absorbing atom. X‐Ray absorption near‐edge structure shows slight modification in the white line feature and some disorder compared to the synthetic one. Reduced coordination number observed from extended X‐Ray absorption fine structure suggests the presence of disorder in local structure. Micro‐Raman spectroscopy indicates that crystalline behavior varies across different locations, suggesting that the sample has undergone varying degrees of metamictization, confirming a nonuniform distribution of elements. The work documents and analyses structural evolution within isolated silica tetrahedron network in association of Zr4+ cation as a function of self‐irradiation and recovery over millions of years and correlating the same with optical properties.
