Wavelength Conversion ParticleWCP Series

Image of WCP Series

WCP series contains specialized phosphor within acrylic resin and converts short wavelength light(ultraviolet light) into long wavelength light(visible light). Solar cell modules, which use encapsulation sheets made of these particles, are expected to increase conversion efficiency.


  • High wavelength conversion efficiency, providing long-term durability for PV modules.
  • Good dispersibility in EVA sheets as well as retaining initial transparency, achieved by the composite particles consisting of acrylic resins and specialized phosphors.
  • Existing PV module assembly lines can be adapted.
