A method of manufacturing an organic solar cell is provided. According to the exemplary embodiments of the present invention, a laminate section can be easily removed from a substrate by causing a cleaning unit to move up and down above the substrate or to move forward and backward in a reciprocating manner in the width direction of the substrate. Furthermore, when a contact member is detachably connected to the cleaning unit, the contact member that has been contaminated with a laminate material can be separated from the cleaning unit and easily washed. Also, the laminate section can be removed by spraying a solvent through a discharging unit to dissolve the laminate section, and suctioning the laminate section through a suctioning unit. In this case, the laminate section can be easily removed from the substrate by dissolving the laminate section with the solvent.
