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.
