An electrode structure is disposed on a substrate of a solar cell. The electrode structure includes a plurality of bus electrodes, a plurality of finger electrodes, and at least one connection electrode. The bus electrodes are separately disposed on the substrate. The finger electrodes are disposed on two sides of the bus electrodes and electrically connect to the bus electrodes. The connection electrode is disposed on a side of the substrate and connects with at least two finger electrodes. The connection electrode, bus electrodes and the finger electrodes are formed by at least two screen printing processes, and at least one of the screen printing processes does not form the bus electrodes. Thus, the thicknesses of the finger electrodes are greater than those of the bus electrodes. |
