“…3d). 51 Compared with traditional organic solvents (DMF and DMSO), which can be transformed into PbAc 2 and dissolved in MAAc solvent, the results reveal a noteworthy advancement. This transformation has been observed to slow down the crystallization of perovskite films during crystal growth, facilitating the preparation of fully covered and smooth perovskite films at ambient air temperature.…”

“…À -, PbAc 2 À -, and PbCO 3 À -based devices achieved 14.48%, 19.21%, and 20.13%, respectively. [47] Wu et al found that the excess lead halides (PbCl 2 , PbBr 2 , PbI 2 ) could form MAPbX 3-x Ac x (X = Cl, Br, I) nanocrystals with the MAAc, thus regulating perovskite growth. [48] As a result, the PbCl 2 -modified devices improved the PCE from 17.80% to 21.26%.…”

Although the power conversion efficiency of perovskite solar cells (PSCs) has reached 25.7%, there is still great potential for improvement in their performance and stability. In the past few years, ionic liquids (ILs) have been extensively investigated and demonstrated to enhance the efficiency and stability of devices substantially. Herein, the role of ILs in PSCs as additives, solvents, interface engineering, and charge transport layer is reviewed. Also, this review will guide the researchers in understanding bulk doping and interface engineering for efficient and stable PSCs.

“…As an alternative to more common high-toxicity and coordination solvents like N, N-dimethylformamide (DMF), and dimethyl sulfoxide (DMSO), proton amine carboxylic acid ILs have been used as precursor solutions for PSCs in a variety of systems. [22,68] Wang et al innovatively reported using methylammonium acetate (MAAc) as an additive in carbon-based mesoscopic PSCs. [69] In comparison to a control device without MAAc, which exhibited a PCE of 10.90%, the device modified by MAAc demonstrated a higher PCE of 13.54%.…”

In the past decade, perovskite solar cells (PSCs), exhibiting high efficiency, low cost, and flexibility, have made inspiring signs of progress and show great potential in large‐scale commercialization as representative third‐generation photovoltaic technology. Nevertheless, due to the rapid crystallization of perovskite crystals through the solution film‐forming technique, a primary challenge is the fabrication of excellent perovskite films with superior optoelectronic characteristics and good flexibility. However, the defects and lattice stresses generated in the perovskite layer during rapid crystallization might diminish the efficiency, robustness, and reliability of PSCs. To date, a variety of techniques are being identified for strengthening the quality of perovskite films, which includes interfacial engineering, solvent engineering, doping, and additives engineering. Among these strategies, developing effective additives is of utmost importance in controlling the kinetics of perovskite film crystallization, leading to improved device performance and mechanical stability, especially for flexible PSCs (FPSCs). Herein, we retrospect the state‐of‐the‐art additives developed in PSCs during the past few years, such as ionic liquids, polymers, and small organic molecules, and pay particular attention to the advanced progress of additive engineering in FPSCs. Moreover, we put forward critical perspectives on the opportunities and challenges of additive engineering in the future development of PSCs.This article is protected by copyright.
