“…[ 24 ] Recently, two less‐toxic halogen‐free solvents of o ‐xylene (OXY) and 1,2,4‐trimethylbenzene (TMB) were used to replace CB as the solvent of PC 61 BM by Fang et al [ 25 ] Meanwhile, graded hetero‐junction (GHJ) structure was introduced by dissolving PC 61 BM in antisolvent to improve the performance. Wang et al [ 26 ] used anisole (AS), an environment‐friendly solvent, to replace CB for dissolving PC 61 BM. Due to the—OCH 3 functional group, the local electrostatic interaction in AS‐PC 61 BM would be stronger than that in CB‐PC 61 BM, which prevented the aggregation of PC 61 BM during the solvent evaporation process and formed a smooth and dense PC 61 BM film.…”

Organ–inorganic hybrid perovskite solar cells (PSCs) have attracted extensive attention with a certified power conversion efficiency (PCE) beyond 25% due to their superior photoelectric properties. However, most reported high‐efficiency PSCs are fabricated with toxic solvents, which raises a major obstacle for potential commercialization. Herein, the recent research progress of green solvents for high‐efficiency PSCs is summarized from antisolvents, precursor solvents, and solvents for electron/hole transport materials, aiming to promote the development of green solvents for PSCs and meet the requirement of sustainable development of the PSCs field. Future challenges and prospects are also discussed to expedite the rational design of green‐solvent‐processed PSCs.

“…35 On the way to green production of PSCs, it is crucial and urgent to replace the toxic solvents with green ones. [36][37][38] Acetone is a non-toxic, Lewis base solvent with high volatility and low boiling point. Zhang et al used acetone to assist the low-temperature crystallization of CsPbI 2 Br perovskite films.…”

“…Tetraethyl orthosilicate with lower toxicity was also employed as an anti-solvent, leading to a PCE of 17.02% with negligible hysteresis . The use of tetraethyl orthocarbonate, frequently used in the synthesis of pharmaceuticals, as an anti-solvent also brought a promising PCE of 18.15% along with anisole as an ETL (phenyl-C61-butyric acid methyl ester) solvent . Meanwhile, various hydroxyl alcohols including ethanol, isopropanol, , isobutanol, and sec -pentyl alcohol were also examined as green anti-solvents but attained relatively poor performance.…”

Remarkably, more sophisticated handling of crystal growth can be accomplished by using a combination of anti-solvents, similar to the solvent blend for perovskite precursor solution.…”

Persistent efforts toward an implementation of green chemistry are highly encouraged in perovskite solar cells (PSCs) research not only because the sustainable chemistry is ideally inseparable from the renewable photovoltaic technology but also because commercialization of PSC practically demands a green technology to reduce its impact on the environmental, health, and safety (EHS). In this Review, we thoroughly examine the materials used in PSCs to assess their potential hazards from the perspective of EHS, followed by an introduction to recycling technologies for PSCs that offer feasible and rational strategies to resolve those issues. In addition to the materials, solvents are taken into consideration due to their importance in determining the occupational risk during mass production of PSCs via solution processes. Progress in the development of green solvents to protect the health of the workforce and to maintain safety in the workplace is accordingly highlighted. Lastly, we carefully propose an overall perspective with a discussion of the remaining challenges facing the development of the environmentally viable PSCs.
