Abstract
A method for manufacturing a solar cell includes forming an impurity doped region of a second conductive type at a substrate of a first conductive type, sequentially irradiating laser shots onto the impurity doped region of the substrate to form an emitter part including 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, and forming a plurality of first electrodes connected to the second emitter region and forming a second electrode connected to the substrate.
