Definition

A specific chemical compound, commonly abbreviated as EDAI in its salt form, used here as a passivation layer to improve the interface quality of the perovskite solar cell.

Etymology

The name is a systematic chemical term derived from ethylene (a two-carbon hydrocarbon chain) and diammonium (indicating two ammonium groups). It follows the conventions of organic chemical nomenclature to precisely describe the molecular structure.

In the news

The researchers used ethylenediammonium diiodide (EDAI) as a passivation layer at the upper interface of their perovskite cell to help stabilize the device performance. It is a critical component in ensuring the efficiency and reliability of the tandem solar cell structure.
