Abstract: The present invention relates to a colored tandem solar cell module, and more particularly, a high-efficiency thin-film colored tandem solar cell module which does not require separate photocurrent matching, implements a color without a separate color filter, and generates power with high efficiency. According to the present invention, it is possible to provide a colored tandem solar cell module including solar cells, which each include a bottom electrode having an inverse diode structure formed by sequentially stacking a first electrode, a first semiconductor layer, a second semiconductor layer, and a second electrode on a substrate, a light absorption layer formed on the bottom electrode, and a top electrode formed on the light absorption layer, thereby eliminating the need for photocurrent matching, implementing a color without a separate color filter, and improving efficiency.

Abstract: Provided is a method of fabricating a see-through thin film solar cell, the method including preparing a substrate including a molybdenum (Mo) layer on one surface, forming see-through patterns by selectively removing at least parts of the Mo layer, sequentially depositing a chalcogenide absorber layer, a buffer layer, and a transparent electrode layer on the substrate and the Mo layer including the see-through patterns, and forming a see-through array according to a shape of the see-through patterns by removing the chalcogenide absorber layer, the buffer layer, and the transparent electrode layer deposited on the see-through patterns, by irradiating a laser beam from under the substrate toward the transparent electrode layer.
