Method for fabricating flexible semiconductor electrode, semiconductor electrode fabricated thereby, and solar cell using the semiconductor electrode

A method for fabricating a flexible semiconductor electrode, the method comprising:

• preparing a first substrate comprising a semiconductor layer disposed on a release layer;
• forming a second substrate comprising 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 to form the flexible semiconductor electrode;
• wherein preparing the first substrate comprises:
• depositing a catalytic metal layer on a substrate;
• coating the catalytic metal layer with the semiconductor layer;
• heating the semiconductor layer;
• and
• forming the release layer at an interface between the catalytic metal layer and the semiconductor layer, and
• wherein the semiconductor layer comprises a metal oxide selected from the group consisting of TiO2, ZnO, Nb2O5, WO3, SnO2 and MgO.
