In our research we developed perovskite crystallization process by modification of dipping time, temperature for better surface coverage and effective charge collection for p-i-n structure out of glove-box in ambient condition and humidity. We also fabricated devices with deposition of all layers fully out of glove-box except contact which shows promising results. We also optimize the multilayer deposition for transport layer can significantly increase Jsc as well FF and overall efficiency. The optimized dip-coating procedure, consisting in a 30 min dipping time for multication perovskite, achieved a champion device with power conversion efficiency of 15.6 % whereas MAPbI3 devices reached exceeding 14 %.
