  • Patent number: 9206339
    Abstract: A method of preparing a polyester/polyolefin hot-melt adhesive for use in a solar cell bus bar is disclosed, in which 2,6-naphthalenedicarboxylic acid and ethylene glycol are first sequentially subjected in a predetermined ratio to esterification and polycondensation in the presence of a certain amount of a titanium-based catalyst to result in a polyethylene naphthalate (PNT) with a weight-average molecular weight of 16,000˜20,000. The PNT is then melt-blended with a low-density polyethylene (LDPE) in the presence of a compatibilizer to produce the hot-melt adhesive that can be shaped into films having a high light transmittance, good mechanical properties, high heat and yellowing resistance and thus particularly suitable for use in solar cell bus bars.

  • Publication number: 20130201605
    Abstract: Technologies are generally described for a nanocomposite polymer dielectric that may incorporate two types of nanoparticles and a polymer. One of the two types of nanoparticle may be a first, smaller nanoparticle, that may occupy spaces between larger second nanoparticles. Another of the two types of nanoparticle may be the second, larger, “high-?” nanoparticle, which supports the overall dielectric constant of the material. In an applied electric field, the first, smaller nanoparticle may redistribute local charge to homogenize electric fields in the dielectric material, tending to avoid the development of “hot spots”. Such a two-nanoparticle nanocomposite dielectric material may provide increased dielectric breakdown strength and voltage endurance in comparison with a nanoparticle dielectric which only contains a single type of “high-?” nanoparticle.
