  • Publication number: 20080169023
    Abstract: An encapsulation material for a solar cell element containing an ethylene-polar monomer copolymer having polar monomer unit content of 10-40 wt % and melting point of not lower than 75° C. and HAZE of not more than 10% and meeting the condition of ?3.0X+125?T??3.0X+109, wherein T is melting (° C.) and X is polar monomer unit content (mol %). The encapsulation material for a solar cell element does not require the use of any organic peroxide, consequently bringing about an improvement in the efficiency in the production of solar cell modules. The encapsulation material can also exhibit excellent transparency, heat resistance and flexibility as will make a reduction in the thickness of solar cell elements adequately possible. A solar cell module using the encapsulation material is also provided.

  • Patent number: 6852792
    Abstract: This invention is directed to the discovery that ethylene-acid copolymers that have low melt flow index MFI (namely less than 100 g/10 min measured according to ASTM D1238 at 190° C., 2.16 kg) even with low acid content (such as less than 20 wt. %) can provide stable aqueous dispersions directly in aqueous media (i.e. free from any other solvent) with less than 1 wt. % non-dispersibles in single bases even at mild dispersion process conditions, at temperature less than 100°C., atmospheric pressure, and with low agitation speed.
