Abstract: A thin-film solar cell allowing for transparency, according to an embodiment of the present invention, comprises: multiple first electrode layers disposed on the top portion of a glass substrate so as to be spaced apart from each other on the glass substrate and have a predetermined pattern; a lower end layer disposed below the first electrode layers; an upper end layer disposed between the first electrode layers and the lower end layer, and formed on the top surface of the lower end layer through a dry etching process by using the first electrode layers as masks; and a barrier layer disposed in an area of the top surface of the lower end layer other than an area in which the upper end layer is formed.
