SOLAR CELL

摘要

A solar cell of the present invention includes a substrate; an emitter part which is located in a first surface of the substrate and forms the p-n junction with the substrate; a first electrode part which is located in the first surface of the substrate and is connected to the emitter part; a second electrode part which is located on a second surface of the substrate which is opposite to the first surface and is connected to the substrate. The first electrode part includes first finger electrodes which are extended in a first direction. The first finger electrodes are separated from adjacent finger electrode. A diffused reflection coating layer is formed on the upper surface of the first finger electrodes.
