“…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).…”

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.

“…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 .…”

“…7 When the second stage is changed to vapor conversion, the PbO 2 film can also be used to react with HI vapor for the conversion of PbI 2 , which was then exposed to CH 3 NH 3 I vapor for the synthesization of the CH 3 NH 3 PbI 3 film. 8,9 Lee et al used the PbO 2 film to react with the gas of 4% H 2 /Ar for the conversion of PbO, which can also be exposed to CH 3 NH 3 I vapor for the synthesization of the CH 3 NH 3 PbI 3 film. 8,9 Besides, by immersion of the PbO 2 film into the solution of CH 3 NH 3 I/isopropanol, the CH 3 NH 3 PbI 3 film can also be obtained directly through the reaction of PbO 2 and CH 3 NH 3 I at temperatures from −2 to 75 °C, where the as-grown CH 3 NH 3 PbI 3 film begins to dissolve apparently at a temperature of ∼55 °C.…”

“…Generally, the perovskite film preparation methods include spin coating, drop casting, thermal evaporation, pulsed laser deposition, blade coating, spray coating, electrodeposition, etc. − Among all of these fabrication methods, the electrodeposition method is a cost-effective, large-scalable, highly reproducible, environmentally friendly, and flexible fabrication technique, which will have a place in the large-scale manufacturing process for perovskite solar cells in the future. At the same time, with the continuous in-depth study of the electrodeposition method in recent years, some exciting achievements have been obtained. − …”

“…The hybrid organic–inorganic perovskite CH 3 NH 3 PbI 3 film was first synthesized by the electrodeposition method in three stages: electrodeposition of the PbO 2 film and transformation into PbI 2 and the CH 3 NH 3 PbI 3 film in order . When the second stage is changed to vapor conversion, the PbO 2 film can also be used to react with HI vapor for the conversion of PbI 2 , which was then exposed to CH 3 NH 3 I vapor for the synthesization of the CH 3 NH 3 PbI 3 film. , Lee et al used the PbO 2 film to react with the gas of 4% H 2 /Ar for the conversion of PbO, which can also be exposed to CH 3 NH 3 I vapor for the synthesization of the CH 3 NH 3 PbI 3 film. , Besides, by immersion of the PbO 2 film into the solution of CH 3 NH 3 I/isopropanol, the CH 3 NH 3 PbI 3 film can also be obtained directly through the reaction of PbO 2 and CH 3 NH 3 I at temperatures from −2 to 75 °C, where the as-grown CH 3 NH 3 PbI 3 film begins to dissolve apparently at a temperature of ∼55 °C . Katrib et al also used electrodeposited PbO 2 for converting mixed halide perovskites, and the record efficiency of the corresponding perovskite solar cells can be improved to 10% with an optimized solar cell architecture, chlorine addition, and carbon electrode. − In addition to PbO 2 , it has been reported that the electrochemical synthesis of PbI 2 , PbO, , PbS, , and metal Pb , can also provide the lead source for the synthesized perovskite CH 3 NH 3 PbI 3 film.…”

Clarifying the crystallization process of the perovskite FAPbI 3 film is quite an important pathway for improving the performance of perovskite solar cells, and the annealing time is a key factor to control the nucleation and crystal growth. However, the existing electrodeposition method lacks systematic studies on the growth of the perovskite FAPbI 3 film. Herein, we manipulate the annealing time precisely for growing a pure α-FAPbI 3 perovskite film in the electrodeposition-assisted method. The perovskite pure α-FAPbI 3 film can be synthesized by fast annealing in only 1 min, and the as-prepared perovskite film shows high solar light absorption capacity and large grains. Thus, the corresponding solar cells based on α-FAPbI 3 show the best power conversion efficiency (PCE) of 13.33%, which is 32% higher than that of FAPbI 3 solar cells annealed for a long time (20 min). More importantly, all of these PCE variances do not exceed 1% under different annealing times, indicating the high reproducibility of the perovskite solar cells based on this rapid crystallization method. With a phenethylammonium iodide passivation layer, the PCE can even be improved to 14.02%.

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.
