The roll-to-roll revolution to tackle the industrial leap for perovskite solar cells

Can Roll-to-Roll technology pave the way for perovskite devices to transition from lab-scale to industrial applications? It is a technique that has the potential to enhance throughput, reduce costs, and accommodate flexible substrates. In a Roll-to-Roll system, as long as your input materials are continuously topped up, manufacture should continue indefinitely. In its simplest form it offers the premise of Ink-IN / Solar module-OUT. Through this comment, we emphasize the critical need for ongoing innovation to fully harness Roll-to-Roll technology's capabilities, making perovskite solar energy a viable, sustainable option on a global scale. Roll-to-Roll (R2R) coating is a technology that potentially enhances throughput, reduces costs, and accommodates flexible substrates for fabricating various types of solar cells and modules. Here, authors discuss the R2R revolution to tackle the industrial leap for perovskite photovoltaic devices.
