RESIN COMPOSITION FOR SOLAR CELL ENCAPSULANT, AND SOLAR CELL ENCAPSULANT AND SOLAR CELL MODULE USING THE SAME |
摘要 |
Provided are a resin composition for solar cell encapsulant which contains an ethylene/a-olefin and is satisfactory in terms of crosslinkability, heat resistance, transparency, and impact resistance, a solar cell encapsulant formed from the resin composition, and a solar cell module obtained using the resin composition. Provided are a resin composition for solar cell encapsulant and the likes, which comprises an ethylene/a-olefin copolymer (A) having the following properties (a1) to (a3) and organic peroxide (B):;(a1) a branch number derived from comonomer (N) and a total number of vinyl and vinylidene (V) in the ethylene/α-olefin copolymer satisfy the following relationship of expression (1): N×V≧10, wherein N and V are the number, as determined by NMR, per total of 1,000 carbon atoms contained in the main chain and side chain,;(a2) an MFR (190° C., 21.18-N load) is 0.1-100 g/10 min, and;(a3) a density is 0.860-0.920 g/cm3. |

1. A resin composition for solar cell encapsulant which comprises the following component (A) and component (B):
component (A): an ethylene/α-olefin copolymer having the following properties (a1) to (a3):
(a1) a branch number derived from comonomer (N) and a total number of vinyl and vinylidene (V) in the ethylene/α-olefin copolymer satisfy the following relationship of expression (1):
