SOLAR CELL

摘要

A solar cell includes a semiconductor wafer, plural finger electrodes, at least one bus electrode, and at least one finger loop electrode. The semiconductor wafer has a light-receiving surface. The finger electrodes are arranged along a first direction and disposed on the light-receiving surface. The bus electrode is arranged along a second direction and disposed on the light-receiving surface, and the bus electrode is connected with the finger electrodes, in which the second direction is perpendicular to the first direction. The finger loop electrode is substantially arranged along the second direction and disposed on the light-receiving surface, and the finger loop electrode is connected to at least two of the finger electrodes, in which the finger loop electrode has a shape of non-square periodic wave.
