Abstract: The present invention relates to a method for manufacturing a solar cell comprising a selective emitter, the method comprising the steps of: forming an electrode pattern and an alignment mark by performing a first impurity doping locally on one surface of a substrate; and performing a second impurity doping on the entire surface of the first doped substrate, wherein, as a result of the first and second doping, the alignment mark is formed on a first emitter or a second emitter, and the electrode pattern is formed on the second emitter. When manufacturing the selective emitter, the alignment mark is formed by doping processes. The use of the alignment mark may increase the matching of the electrode pattern formed in the selective emitter and the resulting electrode line. Further, a solar cell having the selective emitter has excellent conversion efficiency and a high fill factor value.
