Quantum dot

It is possible to generate more power by scattering quantum dots onto the surfaces of solar panel glasses, EVA sheets and silicone cells, and by transforming unused UV lights/infrared lights in solar energy generation into a visible light region (500-600nm region).

Main products
  • Core/shell type of ZnSe/ZnS (Zinc Selenide/Zinc Sulfide) ZnSe/ZnS
  • Core/shell type of InP/ZnS (Indium/Zinc Sulfide)
  • Core/shell type of CdSe (CdS)/ZnS (Cadmium Selenide (Cadmium Sulphide) Zinc Sulfide)
  • Up-converted type
Nanoparticles for coating solar cells

We provide nanoparticles in the power generating body of chemical agent based solar cells. Coating compound semiconductor solar cells by liquefaction of dispersed solvent and water is possible.

Easy dispersion

Forming of solar cell by coating (Roll to Roll can be considered)
