The article discusses the potential of Roll-to-Roll (R2R) technology to revolutionize the production of perovskite solar cells, transitioning them from lab-scale to industrial applications. R2R coating offers several advantages, including enhanced throughput, reduced costs, and flexibility in substrate usage. This technique continuously deposits inks onto flexible substrates, eliminating the need for manual substrate replacement and reducing initial investment costs. It also promotes the use of low-cost, high-performance materials like carbon inks, further lowering production costs. R2R coating is particularly beneficial for perovskite photovoltaics (PV) due to its scalability, automation, and reduced material waste. It enables rapid, large-scale production without a proportional increase in operational costs, making it a key enabler for meeting growing demand for renewable energy. Additionally, R2R coating is more energy-efficient than traditional batch processing methods, reducing energy waste and operational inefficiencies. However, transitioning from spin coating to R2R coating presents significant technical challenges, such as precise control over coating parameters and managing variations in substrate properties. Recent breakthroughs have successfully achieved fully R2R-coated perovskite solar cells, using carbon for the top electrode, which bypasses the need for expensive metals and enhances scalability and sustainability. The future of R2R perovskite devices lies in further refining coating parameters, optimizing module design, and integrating quality control mechanisms. Environmental considerations, such as toxicity and sustainability, are crucial for the widespread adoption of perovskite solar cells. Innovations in substrate materials and recycling protocols are essential to minimize environmental impact and ensure long-term durability. In conclusion, R2R fabrication offers a promising pathway for scaling up perovskite PV cell and module production, but it requires ongoing innovation and collaboration between academia and industry to address technical and environmental challenges.The article discusses the potential of Roll-to-Roll (R2R) technology to revolutionize the production of perovskite solar cells, transitioning them from lab-scale to industrial applications.
