TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: The frame body is formed of a metallic material or a plastic material. The step (d) comprises: attaching a polymer strip formed of the sealant material around the outer periphery of the solar cell module and attaching the outer periphery of the solar cell module, or attaching the polymer strip formed of the sealant material over the inside of the groove portion of the frame body; and extrusion coating the sealant material around the outer periphery of the solar cell module and attaching the outer periphery of the solar cell module into the inside of the groove portion of the frame body, or extrusion coating the sealant material over the inside of the groove portion of the frame body. The method further comprises (e) subjecting the framed solar cell module obtained in the step (d) to curing at a temperature of greater than or equal to 135 degrees C, preferably 140-180 degrees C, where the curing duration is 5-60 (preferably 5-20) minutes.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The sealant material comprises a product of cross-linking the cross-linkable blend composition, where in the product at least a portion of the carboxylic acid groups comprised in the ethylene copolymer-1 are reacted with at least a portion of the epoxy groups comprised in the ethylene copolymer-2 to form cross-links between the ethylene copolymer-1 and the ethylene copolymer-2. The weight ratio of the ethylene copolymer-1 and the ethylene copolymer-2 comprised in the cross-linkable blend composition, is 80:20-20:80, 70:30-30:70, or 60:40-40:60. The first olefin is methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, butyl acrylate or butyl methacrylate. The second olefin is an acrylic acid or a methacrylic acid. The ethylene copolymer-1: comprises 5-40 (preferably 10-30) wt.% of copolymerized units of the first olefin or 5-20 (preferably 5-15) wt.% of copolymerized units of the second olefin; has a melt flow rate of greater than or equal to 5 g/10 minutes, or 30 g/10 min or higher, or 30-500 g/10 minutes, as determined in accordance with ASTM D1238 at 190 degrees C under a weight of 2.16 kg; and is a copolymer of ethylene/n-butyl acrylate/acrylic acid. The ethylene copolymer-2: comprises 3-10 (preferably 4-7) wt.% of copolymerized units of the third olefin or 5-40 (preferably 20-35) wt.% of copolymerized units of the first olefin; has a melt flow rate of 5-300 (preferably 5-100) g/10 minutes, as determined in accordance with ASTM D1238 at 190 degrees C under a weight of 2.16 kg; and is a copolymer of ethylene/n-butyl acrylate/glycidyl methacrylate.
