PROBLEM TO BE SOLVED: To provide a solar cell of a new structure different from conventional ones, capable of increasing a light receiving area by using ball-shaped or polyhedron-shaped photoelectric effect generation bodies, and reducing manufacturing costs as well by utilizing a PCB board structure.SOLUTION: The present invention discloses a solar cell using a PCB including: a board made of an insulating material in which a plurality of fixing holes and conduction holes are alternately penetrated and formed; a plurality of photoelectric effect generation bodies which have ball shapes or polyhedron shapes to be fixed to the board so as to be arranged on the fixing holes, receive light via an exposure area exposed at an upper part of the substrate, and generate photoelectric effects; a plurality of upper electrodes which are formed on the top face of the substrate, and coupled to light receiving areas of the respective photoelectric effect generation bodies; and a plurality of lower electrodes which are formed on the bottom face of the board so as to be coupled to non-light receiving areas of the respective photoelectric effect generation bodies, and conducted with the upper electrodes via the conduction holes. |
