It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
We have studied the optical properties of thin films of organometallic halide perovskites with variable content of iodine and bromine, which were obtained by two-stage deposition from solution. The results are indicative of an increased contribution of excitons to light absorption at the bandgap edge in bromine-containing perovskites as compared to the iodine-containing ones. The possibilities of using perovskites with preset halogen composition in cascade solar cells are discussed.
