Breakthrough Phosphor Coated Sealant Improves Efficiency by 2.2%
Hitachi Chemical will begin mass production of wavelength conversion particles (WCP), which can be applied to EVA sealants for crystalline silicon components, and are said to increase conversion efficiency (relatively) by up to 2.2% over standard sealants. The company says that material manufacturers mix fluorescent materials distributed in acrylic resin particles with EVA encapsulation sheets to obtain short wavelength light (ultraviolet light) and convert it to long wavelength light (visible light) for existing films The durability of the formula has no effect. Test for compliance by JISC8919 outdoor cell assembly and output power test method, said to more conventional photovoltaic sealants, and greatly improve the efficiency.
