Ionic liquids and their various analogues are without doubt the scientific sensation of the last few decades, paving the yellow brick road to a worldly version of Oz's green “Emerald city” – a more sustainable society. Their versatile suite of properties, originating from an almost inconceivably large number of possible cation and anion combinations, allows tuning of the structure to serve a desired purpose. Ionic liquids hence offer a myriad of useful applications from solvents to catalysts, through to lubricants, gas absorbers and azeotrope breakers. The purpose of this review is to explore the more unexpected of these applications, particularly in the energy space. It guides the reader through the application of ionic liquids and their analogues as i) phase change materials (PCMs) for thermal energy storage, ii) organic ionic plastic crystals (OIPCs), which have been studied as battery electrolytes and in gas separation, iii) key components in the nitrogen reduction reaction (NRR) for sustainable ammonia generation, iv) as electrolytes in aluminum ion batteries, and v) in other emerging technologies. We conclude that there is tremendous scope for further optimizing and tuning of the ionic liquid in its task, subject to sustainability imperatives in line with current global priorities, assisted by artificial intelligence.This article is protected by copyright.

“…In addition to conventional organic solvents, novel ionic liquids have also been developed as solvents, which can regulate the crystallization process of perovskites through interface modification, energy alignment, or defect passivation. [ 188 , 189 , 190 , 191 ] Wang et al. introduced the ionic liquid methylamine acetate (MAAc) as a co‐solvent into MAPbI 3 precursor solution to regulate the crystallization process and pore filling of perovskite in mesoporous ETL ( Figure 17 a,b ), [ 192 ] Due to the strong Pb−O interaction between MAAc and PbI 2 and the formation of N−H···I hydrogen bond, the mesophase of MAPbI 3−X (Ac) X will form, which effectively retards the crystallization rate of perovskite phase.…”

As a key contender in the field of photovoltaics, third‐generation thin‐film perovskite solar cells (PSCs) have gained significant research and investment interest due to their superior power conversion efficiency (PCE) and great potential for large‐scale production. For commercialization consideration, low‐cost and scalable fabrication is of primary importance for PSCs, and the development of the applicable film‐forming techniques that meet the above requirements plays a key role. Currently, large‐area perovskite films are mainly produced by printing techniques, such as slot‐die coating, inkjet printing, blade coating, and screen‐printing. Among these techniques, screen printing offers a high degree of functional layer compatibility, pattern design flexibility, and large‐scale ability, showing great promise. In this work, the advanced progress on applying screen‐printing technology in fabricating PSCs from technique fundamentals to practical applications is presented. The fundamentals of screen‐printing technique are introduced and the state‐of‐the‐art studies on screen‐printing different functional layers in PSCs and the control strategies to realize fully screen‐printed PSCs are summarized. Moreover, the current challenges and opportunities faced by screen‐printed perovskite devices are discussed. This work highlights the critical significance of high throughput screen‐printing technology in accelerating the commercialization course of PSCs products.

The production of pure formamidinium lead iodide (FAPbI3) is crucial to ensure high‐ efficiency perovskite solar cells and such pure FAPbI3 is obtainable from crystallization process because impurities from the reagents are removable by molecular recognition effect. In addition, it is important to develop a green crystallization process for the production of FAPbI3 single crystals. Via broad screening of chemicals, here, we select triethylphosphate (TEP) and acetonitrile (ACN) as non‐toxic solvent and antisolvent, respectively, for the liquid‐liquid reaction of FAI and PbI2 and the anti‐solvent crystallization. The new green crystallization process produces pure δ‐FAPbI3 single crystals, which are applicable to fabricate α‐FAPbI3 perovskite solar cells. Due to the reduced trap states in the δ‐FAPbI3 single crystals, the corresponding α‐FAPbI3 perovskite solar cells have 22.61 % efficiency (average = 20.65 ± 0.86 % across 50 devices) and show good operational stability under continuous 1 sun illumination at 50 oC for 1000 h.This article is protected by copyright.
