Solar cell
A solar cell is discussed. The solar cell includes a substrate of a first conductive type, an emitter region which is positioned at a front surface of the substrate and has a second conductive type different from the first conductive type, a front passivation region including a plurality of layers which are sequentially positioned on the emitter region, a back passivation region which is positioned on a back surface opposite the front surface of the substrate and includes three layers, a plurality of front electrodes which pass through the front passivation region and are connected to the emitter region, and at least one back electrode which passes through the back passivation region and is connected to the substrate.
