Stable and efficient perovskite solar cells via hydrogen bonding and coordination

Abstract

The instability of perovskite solar cells (PSCs) is primarily caused by the unavoidable ion migration in the perovskite layer.

Crystallization control of wide-bandgap perovskites for efficient solar cells via adding an anti-solvent into the perovskite precursor

“…Usually, the vacancy-induced defects could react with oxygen or water from the environment, resulting in decomposition of the perovskite structure. 34–36 As a result, a well-crystallized perovskite with fewer defects showed higher intrinsic stability. Moreover, the improved perovskite film may form better interfacial contact with the charge transport layers, which is another aspect of the higher stability.…”
