Description

General description

Ammonium acetate is a white crystalline water-soluble ammonium salt with unique properties that make it suitable for use in solar cells, batteries, and fuel cell catalysts.

Application

Ammonium acetate can be used:

• To passivate CsPbI₃ perovskite nanocrystals for red LEDs. Ammonium acetate effectively eliminate undesired surface metallic lead cations and dangling bonds to enhance the stability and photoluminescence quantum yield (PLQY).
• As an additive to fabricate high quality perovskite solar cell with enhanced power conversion efficiency (PCE) of 13.9%. It promotes crystallization and improve performance without changing the perovskite composition.
• As a cost effective and green electrolyte for all-organic battery-supercapacitor hybrid device with maximum energy density.
• As an electrolyte additive for aqueous zinc batteries. It helps to improve cycling stability and capacity retention.
