“…This morphology is typical for PbI 2 converted from PbO 2 . 19,20,26 In the case of the planar substrate (ITO and SnO 2 ), a direct relation between the PbI 2 platelet size and the PbO 2 grain size is evident. SnO 2 prevents larger PbO 2 grains and greater PbI 2 platelets.…”

“…The PK1 converted MAPbI 3 is in the form of nonuniformly oriented rectangular-shaped grains. ,,, Much smaller grains randomly oriented appear for PK2, with cubic shapes. The morphologies (size and shape of the grains) are very different from the ones traditionally obtained with spin-coated perovskites.…”

“…There have been several attempts over the past few years to optimize the electrodeposited perovskite layer and adjust its crystallization on dissimilar layers. All subtechniques started by electrodepositing an initial layer (PbO, PbO 2 , or PbI 2 ) followed by one or several conversions of the as-deposited layer. − Cui et al and Huang et al both deposited PbO as a first step, before conversion into perovskite. , Cui chose a two-step conversion, first by exposing the as-prepared PbO films to iodine vapor and then converting into perovskite by immersion in methylammonium iodide (MAI) . He was able to develop a gold-electrode-based solar device with a 9% power conversion efficiency (PCE).…”

“…This offers great potential for production cost control. In the nine existing publications ,,− ,,, about perovskites obtained starting from electrodeposited PbO 2 , four use the galvanostatic mode and five use the potentiostatic mode. However, none of the galvanostatic studies have presented the PV data for MAPbI 3 .…”

The electrodeposition technique was explored as a powerful method for perovskite fabrication. It possesses the ability to elaborate high-quality perovskite layers on large-size substrates, with minimal manufacturing costs. In this work, the electrodeposition of PbO2 was conducted as a first step to elaborate MAPbI3 perovskite layers. Two conversion routes have been considered to reach the perovskite film. The first one is an immediate conversion of PbO2 into PK1 by immersion in methylammonium iodide (MAI, CH3NH3I) solution. The second route is a two-step conversion: initial PbO2 conversion into PbI2 by immersion in hydrogen iodide (HI), followed by PbI2 conversion into PK2 by immersion in MAI. For further evaluation of the impact of the conversion pathway and the nature of the substrate, an in-depth study of the microstructure, the morphology, and the key properties for the application of the perovskite layers has been conducted using a set of dedicated characterization techniques. Perovskite solar cells have also been developed using the electrodeposited active layers, which opens the way to promising performances using electrodeposition.

“…At the microscopic scale, the in-plane morphology of the different converted perovskites was studied by SEM and is presented in Figure c. After the conversion of PbI 2 in MAI, the MAPbI 3 surface is completely covered by small cubic-shaped grains with a nonuniform orientation, and a grain size ranging between 150 and 200 nm. ,,, When converting PbI 2 into MAPbI 3– x Cl x , we notice similar surface morphologies for the three films. It consists of cubic grains, a little bigger than MAPbI 3 , more entangled, and less spaced.…”

In this work, electrodeposition was explored as an alternative technique for elaborating large-scale and homogeneous perovskite layers for photovoltaic application. This method was used to elaborate simple MAPbI 3 and mixed halide perovskites MAPbI 3−x Cl x . PbO 2 was first electrodeposited in a controlled manner. Next, the conversion into perovskite was conducted with various iodine/chlorine ratios. This produced different compositions of perovskites combining an interesting range of microstructural and functional properties. These perovskites, obtained for the first time using electrodeposition, were then tested in solar cell devices. The performances obtained with these innovative electrodeposited mixed perovskites are excellent, better than those obtained with most of the common forms of MAPbI 3 published so far. In addition, the stability of these electrodeposited perovskites has been evaluated under mild aging conditions (40 °C, under vacuum or an ambient atmosphere) for 500 h. For the treatment under vacuum, a maturation process was evidenced inducing an improvement of PCE close to 40%, to reach 7%. These results are of great interest, especially considering the active area tested close to 0.2 cm 2 . The addition of Cl in the lattice not only limits the formation of by-products (PbI 2 , MAPbCl 3 , etc.) and enhances the efficiency of the solar cells but also largely increases the stability.

The active layer quality significantly impacts perovskite solar cell performances. In competition with the common spin, the electrodeposition (ED) method has emerged as a cost‐effective, scalable, and environmentally friendly alternative for perovskite deposition. This article combines an up‐to‐date critical review with experimental results for the development of perovskite photovoltaics. The first review section offers a critical understanding of the current state of the art for the processing of perovskite using an ED step. With the comparison of various methods described in the literature, the pros and cons of the technique are reviewed to assess its applicability at the industrial scale. The second part presents experimental findings from the authors, resulting from a 5‐year experience in this area. Various important and specific topics are covered including the optimization of the ED parameters, the influence of the substrate, the material's selection, the architecture, and the impact on active surface properties. The comparison of the performance data from the literature and the new set of experimental data allows to pace the way for the future development and the integration of stable, affordable, and large‐scale photovoltaics cells.
