A team led by Professor Zhou Huanping from Peking University has published two papers in the field of perovskite solar cells ...

Perovskite is subject to ion migration — the movement of ions within the crystal lattice. When exposed to heat and light, electric fields from solar cell components cause ions within the ...

The major cause of instability of perovskite solar cells is believed to be ion migration. They claimed that perovskite solar cells have demonstrated limited operational lifetimes, primarily due to the ...

“In monolithic perovskite solar modules, the migration of ions in the interconnect ... an innovative method for in-situ generation of ion barrier layers, resulting in a substantial enhancement ...

This process also suppressed ion migration and inhomogeneity in the crystallinity of the perovskite, addressing key challenges in device performance. X-ray photoelectron spectroscopy measurements ...

They applied this film in a perovskite-organic tandem solar cell, which exhibited low open-circuit voltage losses and high efficiency levels. December 5, 2023 Emiliano Bellini ...
