PROTECTIVE MATERIAL FOR SOLAR CELLS

摘要

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 0.1 g/m2/day, in which the fluorine-based resin film, the pressure sensitive adhesive layer, and the moisture-resistant film are laminated as a protective material-forming layer P, and the ratio (WP/WA) of the maximum width WP of the protective material-forming layer P other than the fluorine-based resin film to the width WA of the fluorine-based resin film is less than 1.
