Problems solved by technology

[0004] However, these sealing materials have the problem that the strength decreases under high temperature such as direct sunlight, and after softening, they are exposed (extruded) from the frame, which damages the appearance, and as a result, the battery function is damaged due to the intrusion of rainwater, etc.

Embodiment

[0097] Examples are listed below to specifically illustrate the present invention. However, the present invention is not limited by the Examples.

[0098]

[0099] Each component shown in Table 1 below was blended in the composition (parts by mass) shown in Table 1 with respect to 100 parts by mass of butyl rubber, and uniformly dispersed using a universal mixer to obtain a sealant composition.

[0100] Viscosity, shear strength, compression creep during heat, and moisture permeability were measured for each of the obtained sealant compositions in the following manner. The results are shown in Table 1 below.

[0101]

[0102] The viscosity at 190° C. of the sealant composition obtained as described above was measured on the condition of 1 rpm using a rotational viscometer.

Abstract

The invention provides a reaction type hot melting sealing agent composition for a solar cell advantaged by excellent heat resistance and short curing time. The invention provides a reaction type hot melting sealing agent composition for a solar cell comprising butyl rubber and a part of silylanizing crystalline polyolefin polymers with the crystalline temperature of 80-130 DEG C, and provides a solar cell module using the reaction type hot melting sealing agent composition for the solar cell to bond a cell and a frame.

Description

technical field [0001] The present invention relates to a reactive hot-melt sealant composition for solar cells and a solar cell module bonded therewith. Background technique [0002] In recent years, people have paid great attention to the application of solar cells from the perspective of protecting the earth's environment. [0003] Solar cells are often placed outdoors as a module, and the module generally includes a solar cell panel formed by arranging solar cell elements on the light-receiving surface and the opposite surface of a light-transmitting plate, and a frame for installing the solar cell panel. In addition, as a sealing material for fixing and bonding the solar battery panel and the mounting frame, for example, butyl rubbers are used due to their low moisture permeability and low cost (see, for example, Patent Documents 1 and 2). [0004] However, these sealing materials have the problem that their strength is reduced under high temperature such as direct sun...
