Abstract
A method for forming emitter layer of a solar cell includes preparing a substrate including a first impurity of a first conductive type, diffusing a second impurity of a second conductive type opposite to the first conductive type in the substrate to form a first emitter portion of the emitter layer in the substrate, and selectively heating a portion of the first emitter portion, which corresponds to a position for forming at least one electrode, to form a second emitter portion.
