  • Solar cell and method for manufacturing the same
    Patent number: 10483409
    Abstract: A solar cell includes a substrate formed of n-type single crystal silicon, an emitter region of a p-type which is positioned at a first surface of the substrate and includes a first emitter region having a first sheet resistance and a second emitter region having a second sheet resistance less than the first sheet resistance, a plurality of surface field regions of the n-type locally positioned at a second surface opposite the first surface of the substrate, a plurality of first electrodes which are positioned only on the second emitter region to be separated from one another and are connected to the second emitter region, and a plurality of second electrodes which are positioned on the plurality of surface field regions to be separated from one another and are connected to the plurality of surface field regions.
