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.
