NOVELTY - Encapsulant composition (I), comprises: at least one resin monomer, where the resin monomer is acrylic resin monomer, epoxy resin monomer, and/or silicone resin monomer; a filler (0.1-15 wt.%); and a photoinitiator.    USE - (I) is useful for fabricating an encapsulant material, which is useful for packaging a solar cell device and a light emitting element, which is an organic light emitting diode or a light emitting diode (all claimed).    ADVANTAGE - (I) provides the encapsulant material having high light-transmittance, lower production costs, decreased fabrication safety issues and much faster fabrication processes. The encapsulant material exhibits high moisture resistance and gas blocking ability. Light transparency of the encapsulant material can be adjusted by adjusting content of the filler in (I), hence providing the encapsulant material having a light transparency of more than 90%. The encapsulant material has great adhesive strength of up to 2.1 kg/cm. The method does not require controlling reaction pressure and temperature during fabrication of the encapsulant material as all that is required is steady stirring, thus, fabricating method for forming the encapsulant material can be simplified. The method does not require solvent for forming the encapsulant material, thus improving fabrication safety. The encapsulant material is synthesized during fabrication and thus fabrication time is reduced. The filler in the encapsulant material shows great disparity and the moisture and gas proof ability is improved, thus improving operating lifespan of packaged devices.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for fabricating an encapsulant material, comprising providing (I) and performing a first illumination process by a light source, illuminating (I) and polymerizing, thus forming the encapsulant material.
