Title: Makiko Tomiyama: Innovator in Solar Cell Technology
Introduction
Makiko Tomiyama is a prominent inventor based in Yokohama, Japan. She has made significant contributions to the field of solar cell technology, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include a solar cell sealing film and a sealing film for solar cells. The solar cell sealing film is composed of an ethylene-unsaturated ester copolymer, a crosslinker, and crosslinking auxiliary agents. This innovative film features a polyfunctional (meth)acrylate with five or more (meth)acryloyl groups and triallyl isocyanurate as crosslinking auxiliary agents. The mass ratio of the polyfunctional (meth)acrylate to triallyl isocyanurate is carefully balanced at 0.06 to 0.3 parts of polyfunctional (meth)acrylate per one part of triallyl isocyanurate.
The sealing film for solar cells is designed to provide excellent ultraviolet resistance. It includes an ethylene-vinyl acetate copolymer, an organic peroxide, a benzotriazole-based ultraviolet absorber, and a hindered amine-based light stabilizer. The content of the benzotriazole-based ultraviolet stabilizer ranges from 0.01 to 0.3 parts by weight, based on 100 parts by weight of the ethylene-vinyl acetate copolymer. Additionally, the hindered amine-based light stabilizer content is between 0.01 to 2 parts by weight, based on the same quantity of copolymer.
