⭐ This Is How To Make Perovskite Solar Cells ⭐ We’re launching a new video series that shows how perovskite solar cells and modules are made using compact roll-to-roll (R2R) equipment. We use compact, lab-friendly R2R equipment that fits in a regular lab, making it easy to scale your experiments. The series covers: • Substrate preparation • Electron Transport Layer (ETL) • Perovskite active layer • Hole Transport Layer (HTL) • Top electrode • Characterization & performance checks • Practical tip
