The sheet for a photovoltaic cell having excellent moisture barrier property, weather resistance, moisture resistance, thermal resistance, and light resistance, and the photovoltaic module including the same may be provided.
Claims18
A sheet for a photovoltaic cell, comprising:
- a resin layer that comprises a silicon resin which comprises an aryl group, of which a molar ratio of the aryl group with respect to silicon atoms comprised therein is more than 0.3, and which comprises a siloxane unit of Formula 1 or 2;
- and
- a light resistance providing agent:
- (R1R2SiO2/2) Formula 1
- (R3SiO3/2) Formula 2
- wherein R1 and R2 are each independently hydrogen, a hydroxyl group, an epoxy group, an acryloyl group, a methacryloyl group, an isocyanate group, an alkoxy group, or a monovalent hydrocarbon group, at least one of the R1 and R2 is an aryl group, and R3 is an aryl group.

A method of manufacturing a sheet for a photovoltaic cell, comprising:
- forming a resin layer using a liquid coating solution comprising a silicon resin which comprises an aryl group, of which a molar ratio of the aryl group with respect to silicon atoms comprised therein is more than 0.3, and which comprises a siloxane unit of Formula 1 or 2, or a precursor thereof:
- (R1R2SiO2/2) Formula 1
- (R3SiO3/2) Formula 2
- wherein R1 and R2 are each independently hydrogen, a hydroxyl group, an epoxy group, an acryloyl group, a methacryloyl group, an isocyanate group, an alkoxy group, or a monovalent hydrocarbon group, at least one of the R1 and R2 is an aryl group, and R3 is an aryl group.
