<p>PURPOSE: An EVA sheet for sealing a solar cell saves manufacturing costs and uses a heat-sealing powder resin, thereby quickly removing bubbles at modulation and reducing cycle time. CONSTITUTION: An EVA sheet for sealing a solar cell has a heat-sealing layer (200), which is formed on the upper part of a substrate and contains a heat-sealing resin powder including an ethylene-based resin. A manufacturing method of the EVA sheet for sealing a solar cell comprises a step of preparing a substrate (100) by extrusion blow molding; a step of preparing a heat-sealing resin powder (300) including an ethylene-based resin; a step of scattering the heat-sealing resin powder onto the substrate; and a step of curing the heat-sealing resin powder in order to form a heat-sealing layer.</p> |
