Title: Stabilized wide bandgap MAPbBrxI3-x perovskite by enhanced grain size and improved crystallinity

Abstract

In this study, the light instability of CH3NH3PbIxBr3–x has been raised one of the biggest challenges for its application in tandem solar cells. Here we show that an improved crystallinity and grain size of CH3NH3PbIxBr3–x films could stabilize these materials under one sun illumination, improving both the efficiency and stability of the wide-bandgap perovskite solar cells.
