Abstract
A solar cell includes a silicon semiconductor substrate; an emitter layer formed on a surface of the silicon semiconductor substrate; an antireflection layer formed on the emitter layer: and a front electrode electrically connected to the emitter layer by penetrating the antireflection layer. The front electrode includes a finger line and a busbar electrode electrically connected to the finger line, and the busbar electrode includes at least a first electrode line and a second electrode line electrically connected to each other. The first and second electrode lines have a width same as or larger than a width of the finger line, and the first and second electrode lines have the width of 100 μm or less.
