Abstract: According to one embodiment of the present invention, a method for dismantling a solar cell module for recycling comprises the steps of: providing a silicon solar cell module in which a silicon solar cell element and one side of glass are bonded together by a sealing agent and a transparent conductive material layer is coated between the side of the glass and the sealing agent; applying a high voltage between the transparent conductive material layer and the other side of the glass; and separating the glass and sealing agent by exposing the silicon solar cell module having the transparent conductive material layer discolored by application of the high voltage to a moisture environment.
