Study on characterization of cured adhesive by ultraviolet for encapsulation photovoltaic modules

摘要

BIPV is the most important application of PV products, and BIPV solar modules will take a great share of the PV market in the future. BIPV solar modules which encapsulated with UV-cured adhesive is researched in this paper. The refractive index and dielectric constant of the UV curable adhesive films are measured and discussed. It is found that UV curable adhesive refractive index is 1.678 which is approximate with the toughened solar glass. The dielectric constant of UV-cured adhesive is 2.822, the quality of UV curable adhesive film is good with an ideal electricity insulation property. Result shows that this kind of modules encapsulated by UV-cured adhesive not only can absorb daylight fully, but also has a better electricity insulation property. UV-cured solar modules are suitable to be used in building.
