Abstract: The present invention relates to a flexible substrate CIGS solar cell in which a Na supply method is improved. The flexible substrate CIGS solar cell is made of; a substrate of a flexible material; a back side electrode formed on the substrate; a CIGS light absorption layer formed on the back side electrode; a buffer layer formed on the CIGS light absorption layer, and a front side electrode formed on the buffer layer. The back side electrode is a Na added Mo electrode layer which is made of a single layer. The present invention applies the Na added Mo electrode layer which shows low specific resistance of 1/10 than an existing Na added Mo electrode layer and provides a flexible substrate CIGS solar cell of high efficiency which forms a back side electrode into a signal layer. Also, a process which forms a back side electrode is formed of a process which forms the Na added Mo electrode layer of the single layer only. Therefore, a manufacturing process and manufacturing costs of the flexible substrate CIGS solar cell are reduced. Furthermore, the present invention comprises a process of eliminating a Na compound formed on the surface while a Na added metal layer is exposed to air and solves a problem in which a light absorption layer is separated or the conversion efficiency of a solar cell is reduced.
