“…[85,86] Up to date, the reported all inorganic perovskite layer can maintain its absorbance after 100 h at 85 °C under ambient air conditions, and the corresponding all-inorganic devices achieve a PCE of 20.37%. [87] However, the present strategies principally concentrate on interface engineering, [88] additive engineering, [89] and component engineering [90] for the fabrication of efficient all-inorganic PSCs with long-term stability. Regarding green solvent engineering, the research on replacing generally accepted toxic organic solvents system (DMF and DMSO) are rarely mentioned.…”

Solution‐processed perovskite solar cells (PSCs) are widely and dramatically developed with certificated record efficiency up to 25.7%, which have been regarded as the most promising candidates for next‐generation photovoltaic devices. However, the current decent devices are dominantly fabricated based on traditional toxic organic solvents such as N,N‐dimethylformamide and dimethyl sulfoxide, which inevitably leads to environmental damage and potential safety accidents. As green and nontoxic molten salts at room temperature, ionic liquids (ILs) as promising alternatives for traditional toxic organic solvents have attracted intensive research interest worldwide in the field of perovskite photovoltaics with encouraging development. Herein, especially concentrating on ILs solvent engineering rather than additive or post‐treatment, discussion and summarization upon the recent progress on perovskite photovoltaics including both 3D and 2D‐based PSCs is systematically carried out. An in‐depth understanding regarding the interactions between IL molecules and perovskite precursor materials is thoroughly explored and summarized. Moreover, the detailed influence of ILs as solvent(s) on the aspects of perovskite material crystallization regulation, surface defect passivation, and performance improvement of resultant device is comprehensively overviewed and discussed. Finally, prospects of the application of ILs in the PSCs through solvent engineering are provided for further developments.

“…[30] Depending on the organic additive structure and the processing procedure, introduction of the organic additives can affect the perovskite film formation, the defect passivation, and the surface/interface tuning. [31,32] Although, several researchers have reviewed the recent progress in the field of inorganic PSCs and the application of organic additives in inorganic PSCs, [32][33][34][35][36][37][38] a brief summary and discussion of organic additive engineering to control the CsPbX 3 crystallization process and grow high-quality perovskite films is still necessary and important. Considering the rapid development and the unique properties and mechanism of organic additive engineering in improving inorganic perovskite quality and the performance of inorganic PSCs, we provide a detailed overview and deep going discussion by this work.…”

Inorganic CsPbX3 (X: Br, I, or their mixture) perovskite solar cells have gained widespread attention due to their superior stability and the steadily increased conversion efficiency. Inorganic CsPbX3 perovskite for solar cell application are usually fabricated by the solution‐processing method. The nature of solution‐processing method and the rapid crystal growth of perovskite lead to the formation of a wide range of defects within CsPbX3 perovskite films, which deteriorate the performance and stability of CsPbX3 devices. Recently, organic additive engineering has been demonstrated to be an effective strategy for improving the perovskite quality. Herein, the recent progress of organic additive engineering to grow high‐quality inorganic CsPbX3 perovskite films for high‐performance solar cells is summarized. The role of organic additives in the formation of inorganic CsPbX3 perovskite films and their effect on the performance of corresponding perovskite solar cells are discussed. In addition, some issues of organic additive engineering that should be deeply understood are summarized, and the research trend on organic additive engineering for further improving the performance of CsPbX3 devices is suggested.

“…[17][18][19] However, because of the evaporation of DMAI during the annealing stage, it still suffers from poor morphology and vacancy defects. [20][21][22][23] In addition, the sol-gel technique is commonly used for the fabrication of the perovskite film, leading to a polycrystalline absorber layer. Defects would unavoidably arise in the GBs of the films during the production process.…”

High Efficiency Inorganic Perovskite Solar Cells Based On Low Trap Density and High Carrier Mobility CsPbI₃ Films

Inorganic perovskite CsPbI3 has exhibited promising performance in single‐junction solar cells, but the grain boundaries (GBs) in its film cause the formation of the defects with deep energy levels (such as iodide vacancy (VI)) and impede the transport of carriers, worsening the efficiency and stability of the solar cells. Here, a CsPbI3 precursor is devised with thiophenol series ligands (TP‐ligands) containing both SH and π‐conjugated molecules. The strong interaction between the SH group (Lewis base) and PbI2 (Lewis acid) suppresses the formation of PbI42− in perovskite solution, thus suppressing the formation of VI in the film accordingly. The terminal groups, such as ‐F and ‐NH2, are employed to achieve an appropriate evaporation speed of the ligands and prevent the oxidation of the thiophenol group, then a high‐quality perovskite film with low trap density is obtained. In addition, the functional group π‐conjugated molecules provide additional carrier transmission channels at the GBs to increase carrier mobility, which facilitates the exciton separation and prolongs the charge lifetime. The CsPbI3 solar cell shows a considerable power conversion efficiency of 20.1% with an open‐current voltage of 1.18 V and a high fill factor of 83.5% and excellent working stability.
