Abstract
An electrode structure is disposed on a substrate of a solar cell. The electrode structure includes a plurality of bus electrodes and a plurality of finger electrodes. 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 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.
