General description

Potassium dichloroacetate is a white solid compound available as a powder, crystals, or chunks, with a high purity of 98%. It is water-soluble and stable when stored properly, but is hygroscopic and should be handled in a dry, inert atmosphere. This compound is commonly used as a precursor in the fabrication of energy materials, especially for solution and vapor deposition processes, due to its clean decomposition and ability to introduce potassium and chloride ions. Its chemical properties make it ideal for forming thin films and nanostructures in electronic and catalytic applications.

Application

Potassium dichloroacetate can be used as:
  • A bidentate ligand in sequentially deposited perovskite solar cells to improve the power conversion efficiencies and enhance long-term stability.
  • A multifunctional additive in perovskite solar cells, where its dichloroacetate anion passivates defects and suppresses residual PbI₂, and enhances film crystallinity. This action enhances power conversion efficiency and improves long-term stability to devices.(2)

Features and Benefits

  • High Purity (Assay: 98%): Ensures reliable performance and consistency in applications requiring high-grade chemical quality.
  • Versatile Physical Forms: Available as powder, crystals, or chunks, allowing flexibility for different handling, processing, or formulation needs.
