Nitto Denko Corporation introduces the development of an
unprecedented wavelength conversion technology, "RAYCREA," for PV encapsulating sheets. RAYCREA sheets
convert UV-light in sunlight into visible-light with very high efficiency, over 95%. Until now, UV-light
has never been used for power generation. By simply replacing the current encapsulating sheets in a PV
module with RAYCREA, the module power can be increased by about 2%. This brand new, world-class
technology can be implemented to enhance the power of a module with no capital investment or
re-inspection of other components, such as the back sheet.
Nitto will market this technology as not only a product by itself, but also as an additive for existing
PV encapsulating sheets.
These days, PV modules and system have become widespread
thanks to increased social concern with energy saving, CO2 reduction, and sustainable energy. The market
for these products is currently supported by subsidiaries from governments. Thus, power enhancement of
PV modules and reduction of costs are two major concerns. With these factors in mind, Nitto focused on
utilizing UV light in sunlight, energy that is abandoned in current PV technology. Nitto succeeded in
the commercialization of wavelength conversion technology which efficiently uses this energy over a
number of years.
1. High UV Absorbance Due to equal or higher levels of UV
absorbance than conventional encapsulation sheets with normal UV absorbers, it's possible to increase
power output without sacrificing the performance of protection against UV degradation.
2. High fluorescence quantum yield The Fluorescence quantum yield for converting UV-light to
visible-light is over 95%, so that most of photons from UV-light are utilized during wavelength
conversion.
3. High durability During many accelerated tests on PV modules, no reduction in the efficiency of the
product has been observed.
4. No undesirable incidental issues No capital investment or re-inspection of other components is
required.
“RAYCREA” is combination of words “RAY” and “CREA,” or “creation” in Latin.
