Structuring and gripping technology for a material with halide salt protective layer in the quantum dots

 

Client / Market

  • Quantum dot manufacturer, quantum dot film manufacturer, quantum dot display manufacturer

 

Necessity of this Technology

  • Current, research on utilization of QD photovoltaic devices is conducted actively.
    - Display field → Full-scale commercialization began (Samsung)
    - QD photovoltaic device → Photon to electron conversion efficiency over 12%/li>
  • High-stability QD synthesis development is needed to expand fields for application of QD-based photovoltaic devices.

 

Technical Differentiation

  • Can provide high-efficiency QD and QD with great stability.
  • The properties maintain after made as a device that the faulty rate of device decreases.

 

Excellence of Technology

  • Developed high-stability QD synthesis using cation exchange reaction
  • Successful high-stability QD synthesis through phosphonic acid treatment on QD surface
  • Production on inorganic ligand QD solar cell using a multi-scale structure-based iodide ion
  • Successful production of a solar cell with a photon to electron conversion efficiency of 12.3%
  • Published 10 SCI papers including Adv. Mater., J. Am. Soc. Chem., ACS Nano
