Bulk and surface cooperative passivation enables efficient and stable wide-bandgap perovskite solar cells.

Inverted wide-bandgap perovskite solar cells (PSCs) have drawn significant attention due to their excellent optoelectronic properties, low-cost fabrication processes, and good compatibility with tandem devices. However, the presence of bulk and surface defects limits further improvement in their performance. In this wo...
