“…In this case, a monolithic structure with vertical grain boundaries is formed, which favors the fast charge transfer to the contact on both PVK film sides. We have shown that additives such as MACl, [ 37 ] NH 4 Cl, and also gold nanoparticles [ 52 ] allow a change in the growth regime and to access to the lateral growth. The corresponding relative growth parameters are listed in Table 4 .…”

“…Moreover, all measurements were performed under the very same conditions. [51][52][53]56] In order to better understand the different stages of perovskite film formation, we first divided the whole process into two stages: 1) the spin coating and dripping step; 2) the thermal annealing of the obtained precursor films and their crystallization.…”

“…To better understand the depth profile of spincoating processes, Zheng et al developed a quantitative approach based on curve inte gration that allows a clear distinction between the upper and lower layers (see Figure S2, Supporting Information for expla nation). [37,52] In this approach, an area under the curve of the element depth profile in the zone selected as the layer is related to the total (integral) amount of the element in the layer. In this way, the evolution of precursor content (Figure 3c) and total solvent (Figure 3f) in each layer and the contribution of each layer as a function of implemented treatment could be studied.…”

“…Moreover, we have been pioneers in the application of GDOES in the study of the perovskite films formation. [51][52][53] In this review paper, we dis cuss the variety of information that GDOES technique can provide to scientists working on the perovskite films and solar cells. We hope that this focus will convince the perovskite sci ence community of the great potential of this technique to pro vide unique and precious information.…”

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.

Photodetectors play an important role in optical communication systems and are essential to achieve high‐fidelity signal transmission. The emerging formamidinium‐based quasi‐2D layered perovskites have attracted attention in the field due to their excellent photoelectric performance and moisture stability. By optimizing film quality and device engineering a high‐performance flexible photodetector based on formamidinium‐based perovskites ((BA)2FAPb2I7) is developed, which shows fast response and excellent air‐stability. By introducing the formamidinium chloride as an additive the quality and the crystallinity of the film are improved. In addition, localized surface plasmonic resonances (LSPRs) are introduced by embedding Au nanostructures on the substrate, the LSPRs, in turn, enhance light and matter interaction, which further increases the performance of the device. The optimized devices show an ultimate response speed ≈9 µs as well as outstanding long‐term environmental stability (environmental conditions > 1000 h). Achieving such high dynamic range and stability is to the best of authors knowledge rarely reported. The device shows the highest responsivity of 2.3 A W−1, detectivity of 3.2 × 1012 Jones, and outstanding flexibility stability. Finally, the prepared photodetector is successfully integrated into an optical communication system and tested. The results suggest that formamidinium‐based quasi‐2D perovskite photodetectors have great potential in optical communication applications.

The development of an efficient fabrication route to achieve high‐resolution perovskite pixel array is key for large‐scale flexible image sensor devices. Herein, a high‐resolution and stable 10 × 10 flexible PDs array based on formamidinium(FA+) and phenylmethylammonium (PMA+) quasi‐2D (PMA)2FAPb2I7 (n = 2) perovskite is demonstrated by developing SiO2‐assisted hydrophobic and hydrophilic treatment process on polyethylene terephthalate substrate. By introducing Au nanoparticles (Au NPs), the perovskite film quality is improved and grain boundaries are reduced. The mechanism by which Au NPs upgrade the photoelectric quality of perovskite is mainly revealed by glow discharge‐optical emission spectroscopy (GD‐OES) and grazing‐incidence wide‐angle X‐ray scattering (GIWAXS). To further improve the photoelectric performance of the devices, a post‐treatment strategy with formamidinium chloride (FACl) is used . The optimized flexible PDs arrays show excellent optoelectronic properties with a high responsivity of 4.7 A W−1, a detectivity of 6.3 × 1012 Jones, and a broad spectral sensitivity. The device also exhibits excellent electrical stability even under severe bending and excellent flexural strength, as well as excellent environmental stability. Finally, the integrated flexible PDs arrays are used as sensor pixels in an imaging system to obtain high‐resolution imaging patterns, demonstrating the imaging capability of the PDs arrays.
