Crystallinity percentage
WebCrystallinity index is the ratio of the crystalline peaks to the crystalline+amorphous peaks. Amorphous peaks are the noise in XRD data, while, from crystalline+amorphous, we mean the whole XRD... WebFGDYO-SnO 2 film showed the best crystallinity, which could be related to the highest percentage of Sn 4+ and the fewest oxygen vacancies of FGDYO-SnO 2 film. Considering that the cells was most efficient at 30 min of annealing process when we optimized the perovskite cells, we chose to process the ETL layers for 30 min in subsequent experiments.
