PROBLEM TO BE SOLVED: To solve such problems occurring possibly when sealing a solar cell with an embossed polyolefin film, i.e., cracking of solar cell, air entrainment due to poor deaeration when sealing, protrusion of polyolefin resin to the end face of a laminate, and the like.SOLUTION: The method of manufacturing a solar cell comprises: a preparation step S10 of preparing a solar cell sealing film; and a sealing step S20 of forming a laminate by laminating a first solar cell sealing film, a solar cell, and a second solar cell sealing film in this order, and integrating the laminate by heating and pressing. At least one of the first and second solar cell sealing films is provided with recesses in the surface, and has an embossed polyolefin film obtained by depositing polyolefin resin and satisfying a relation 0.05≤V1/V2≤0.8, where V1 is the total volume of recesses per unit area of the film, and V2 is a value obtained by multiplying the unit area by the maximum thickness of the film. |
