SOLAR CELL, MASK FOR FABRICATING SOLAR CELL ELECTRODE AND METHOD FOR FABRICATING THE SOLAR CELL

摘要

The present invention provides a solar cell which promotes stable contact with a ribbon arranged on a front electrode and reduces error rate by forming the front electrode which has an upper surface in a concave shape, and can improve reliability by minimizing damage to a cell. The solar cell includes: a substrate which has a first surface and a second surface which is flat and faces the first surface; an emitter layer formed on the first surface of the substrate; and the front electrode which includes a lower surface facing the emitter layer and an upper surface facing the lower surface, and is electrically connected to the emitter layer on the emitter layer. The upper surface of the front electrode generally has a concave shape.
