Green anti-solvent engineering for high-efficiency and environmentally friendly perovskite solar cells

Area of Science:

• Materials Science
• Renewable Energy
• Environmental Science

Background:

• High-performance perovskite solar cells (PSCs) require flat, dense films with low defect density.
• Anti-solvent-assisted crystallization (ASAC) is effective but often uses toxic solvents like chlorobenzene and toluene.
• Toxic solvents pose risks to human health and the environment, contradicting sustainable development goals.

Purpose of the Study:

• To review recent advancements in green anti-solvents for PSC fabrication.
• To assess the properties and performance impacts of various green anti-solvents and additives.
• To evaluate non-anti-solvent green preparation methods for PSCs.

Main Methods:

• Literature review of research on green anti-solvents in PSCs.
• Analysis of physical and chemical properties of different green anti-solvents.
• Assessment of five types of non-anti-solvent green preparation methods.

Main Results:

• Identified various green anti-solvents and their effects on perovskite film quality and PSC performance.
• Evaluated the use of additives in conjunction with green anti-solvents.
• Assessed alternative physical preparation methods as eco-friendly options.

Conclusions:

• Development of non-hazardous green anti-solvents is vital for sustainable PSC technology.
• Green anti-solvents and alternative methods offer pathways to efficient, stable, and environmentally friendly PSCs.
• This review provides references for manufacturing eco-friendly perovskite devices.
