Disclosed herein is a method for fabricating a flexible semiconductor electrode including preparing a first substrate having a semiconductor layer disposed on a release layer, forming a second substrate having an adhesive layer disposed on a conductive material-coated flexible substrate, and pressing the first substrate against the second substrate under heat effective to transfer the semiconductor layer from the first substrate to the second substrate. The method allows for a flexible semiconductor electrode to be fabricated at low temperatures in a stable manner, and the flexible semiconductor electrode allows for high photoelectric conversion efficiency in a solar cell.
