Wavelength Conversion Technology Lifts Power of PV Modules

摘要

The RAYCREA photovoltaic encapsulation sheets from Nitto Denko Corporation convert ultraviolet light in sunlight into visible light with 95 percent efficiency. By replacing the current encapsulating sheets in PV modules with RAYCREA, the module power can be increased by 2 percent. RAYCREA features high ultraviolet absorbance, thus making it possible to increase power output without sacrificing the perfor- mance of protection against ultraviolet degradation. Its fluorescence quantum yield for converting ultraviolet light to visible light is over 95 percent so that most of the photons from ultraviolet light are utilized during wavelength conversion.
