Publication number: 20140360581Abstract: The present invention achieves a solar cell protective material containing a moisture-resistant film with a moisture vapor permeability of less than 0.1 g/m2/day, but not decreasing the moisture resistance for a long term, preventing delamination, and having excellent flexibility and excellent moisture resistance. The present invention provides a solar cell protective material having an effect in preventing the performance degradation of a solar cell and improving the durability of a solar cell. The solar cell protective material includes a fluorine-based resin film; a pressure sensitive adhesive layer; and a moisture-resistant film having a base material and an inorganic layer on at least one side of the base material, the moisture-resistant film having a moisture vapor permeability of less than 0.Type: ApplicationFiled: December 27, 2012Publication date: December 11, 2014Applicant: MITSUBISHI PLASTICS, INC.Inventors: Naoya Ninomiya, Tetsuya Aya, Osamu Akaike, Hirofumi Kudou, Yumi Mitsukura

Patent number: 7834539Abstract: The electroluminescent device successively comprises a cathode, an electroluminescent layer, a transparent electrode layer, an evanescent light-scattering layer comprising a matrix composed of a low-refractive material containing light-scattering particles, and a transparent sheet/plate. Such an electroluminescent device is decreased in total reflection not only at a boundary surface between a transparent substrate and an outside air layer but also at a boundary surface of the transparent electrode layer on its light extraction side, and therefore, is considerably improved in light extraction efficiency. In addition, in the electroluminescent device provided with a barrier layer, the transparent electrode layer and the electroluminescent layer can be well protected so that deterioration of electroluminescent pigments and occurrence of dark spots can be effectively prevented, resulting in enhanced-life of the device.Type: GrantFiled: October 30, 2008Date of Patent: November 16, 2010Assignee: Mitsubishi Chemical CorporationInventors: Keishin Handa, Shinji Aramaki, Tetsuya Aya
