Solar perovskite production on a roll

Advanced ink formulations could be the key to turning perovskite solar cells (PSCs) from heroes of academic labs into commercially successful products. Researchers at KAUST have developed a perovskite ink tailor-made for a mass manufacturing process called slot-die coating, producing PSCs that captured solar energy with high efficiency. The ink could also be coated onto silicon to create perovskite/silicon tandem solar cells that capture even more of the Sun’s energy.
