Application

  • Extremely hygroscopic.
  • Handle in glove box.
  • Handle and store under nitrogen atmosphere
Guanidinium iodide (GI), a guanidinium compound, exhibits good piezoelectric and pyroelectric properties. It can be used in the fabrication of dye-sensitized solar cells (DSSCs).
Guanidinium iodide anhydrous can be utilized as an ion migration inhibitor or as a dopant in polymer electrolytes for electronic devices. It can be employed as an additive in perovskite solar cells to modify the properties of perovskite layers. It may help in reducing defects, improving the crystallinity, and enhancing the absorption characteristics of the perovskite layer, ultimately leading to improved device performance.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.
