NOVELTY - A thin film solar cell structure comprises a substrate, a front electrode layer, an absorber layer and a back electrode layer, stacked on one another sequentially, and further comprises a panel electrode, and the panel electrode further comprising a cell anode (11) and a cell cathode, and a conductive channel of the cell anode and the cell cathode being formed by patterning a first isolation groove (17), a second isolation groove (18) and a conductive groove (19).    USE - The thin film solar cell structure is used as energy source.    ADVANTAGE - The thin film solar cell structure is a single-deck or multi-deck thin film solar cell structure, and the thin film solar cell comprises a panel electrode formed by a cell anode and a cell cathode. The thin film solar cell structure does not require the design of a conductive ribbon, such that the response area of the thin film solar cell can be expanded to increase the total output of electric power of the thin film solar cell. The thin film solar cell structure does not require a soldering of conductive ribbon, such that the manufacturing procedure of the thin film solar cell can be simplified and the material cost of the conductive ribbon can be saved.    DETAILED DESCRIPTION - A thin film solar cell structure comprises a substrate, a front electrode layer, an absorber layer and a back electrode layer, stacked on one another sequentially, and further comprises a panel electrode, and the panel electrode further comprising a cell anode (11) and a cell cathode, and a conductive channel of the cell anode and the cell cathode being formed by patterning a first isolation groove (17), a second isolation groove (18) and a conductive groove (19). The first isolation groove is penetrated through the back electrode layer and the absorber layer. The second isolation groove is concavely formed on the front electrode layer and filled with an insulative material, and the insulative material of the second isolation groove is provided for electrically isolating a portion of the front electrode layer from the second isolation groove. The conductive groove is concavely formed on the absorber layer and filled with a conductive material, and the conductive material of the conductive groove is provided for achieving an electric conduction between the front electrode layer and the back electrode layer. An INDEPENDENT CLAIM is a method of patterning an electrode of the thin film solar cell structure.
