Deposition technologies of perovskite layer enabling large-area photovoltaic modules

The commercialization of perovskite solar cells (PSCs) is expected. However, the selection of fabrication technology remains unclear, especially with different technologies corresponding to different area ranges. This study presents a summary of recent technologies related to device area and photovoltaic parameters for certain area ranges. Blade-coating, slot-die coating, and bar-coating technologies are suitable for PSCs whose area is greater than or equal to 100 cm2. Meanwhile, meniscus-coating, spray-coating, and roll-to-roll technologies are appropriate for flexible large-area PSCs. The definition of large area has been updated to one above 10 cm2. In conclusion, we provide a perspective for future large-area perovskite photovoltaics.
