“Our study introduces an innovative lead iodide (PbI2) secondary growth and π-π stack regulation strategy that enhances the photovoltaic efficiency and stability of perovskite solar cells ...

The PZ additive was critical in stabilizing lead iodide (PbI2) and FAI during crystallization. Researchers found that PZ formed strong Lewis acid-base pairs with PbI2 and hydrogen bonds with FAI.

Researchers have developed a novel passivation process for formamidinium lead iodide perovskite films, which reportedly resulted in solar cells with 23.69% power conversion efficiency, and modules ...
