Abstract: Abstract Fully ambient, low temperature-processed, and high-performance perovskite solar cells (PSCs) fabricated with sequential deposition method (SDM) are especially attractive for future commercialization. However, it is extremely difficult as uncontrollable crystallization of PbI2 upon deposition…
