Abstract

Perovskite solar cells, despite achieving over 26% power conversion efficiency in labs, face scalability challenges due to limitations in conventional methods like spin coating. This study introduces an optimized blade coating process for fabricating large-area (15 cm × 15 cm) perovskite solar modules with a nickel oxide hole transport layer in ambient air using a non-toxic solvent system. Self-assembled monolayers enhance perovskite film uniformity. Modules with a 110 cm² active area achieve 12.6% efficiency and retain 84% after 1000 hours at 85 °C in air, demonstrating progress towards large-scale, stable perovskite solar cell production.
