چکیده انگلیسی
A texture perovskite (TP) MAPbI3 thin film was developed through the reaction between diluted MA vapor and HPbI3 solid. The XRD intensity of the prepared perovskite without annealing generally can be as high as 106 to 107 which is rarely reported. The high crystallinity of TP is attributed to the excess MA strongly coordinating to Pb (II) and crosslinking adjacent crystals. This excess MA can passivate perovskite surface and grain boundary, leading to 2 months stability under 65% humidity and also substantially improved thermal stability. And the texture perovskite delivered champion PCE 18.9% in the batch production. Therefore, the excess MA coordination in the TP is beneficial for the crystallinity, PCE, stability and scalability together.236
