Inspired from refs (23) and (24). Chemical structures of magnesium acetate, perchlorate, and TFSI – salts are shown. The kosmotropic or chaotropic character of the anion thus plays a critical role in ...

Bifacial perovskite solar cells (PSCs) require micron-thick perovskite layers to compensate for optical loss from transparent electrodes, but high defect densities limit efficiency. Here, we introduce ...
