    Abstract

    In this work the benefit of using optically superior silicone encapsulant materials over the incumbent ethylene vinyl acetate is demonstrated. Optical characterization of the two materials demonstrates improved transmission in the UV region of the solar spectrum. Single cell mini-modules were prepared using two different manufacturers of screen printed textured monocrystalline Si PV cells. Spectral response measurements demonstrate a 0.74-1.03% relative increase in short circuit current density when silicones are used rather than ethylene vinyl acetate, clearly in the region of improved UV transparency. IV measurements demonstrate a 0.31-1.45% improvement in current for silicone.
