Abstract
Provided is an encapsulant for a solar cell which is highly anticorrosive and can form a solar cell module with a long life. Also provided is an interlayer film for laminated glass, which is highly anticorrosive and can form a laminated glass with long-term durability. The encapsulant for a solar cell or the interlayer film for laminated glass includes a material having a polyvinyl acetal content of 40% by mass or more and a chlorine content of 25 ppm or less and having a plasticizer content of 10 parts by mass or less based on 100 parts by mass of polyvinyl acetal.
Claims11
An encapsulant for a solar cell or an interlayer film for laminated glass, comprising a material having a polyvinyl acetal content of 40% by mass or more and having a plasticizer content of 10 parts by mass or less based on 100 parts by mass of polyvinyl acetal.
A method for producing the encapsulant for a solar cell or the interlayer film for laminated glass, the method comprising performing acetalization of a polyvinyl alcohol with an aldehyde to obtain the polyvinyl acetal, wherein a chlorine-free catalyst is present in the acetalization.
