SOLAR CELL AND SOLAR CELL PANEL INCLUDING THE SAME

摘要

A solar cell is disclosed. The disclosed solar cell includes a semiconductor substrate, a conductive region disposed in or on the semiconductor substrate, and an electrode including a plurality of finger lines connected to the conductive region, and formed to extend in a first direction while being parallel, and 6 or more bus bar lines formed to extend in a second direction crossing the first direction. Each bus bar line has a width of 35 to 350 μm at at least a portion thereof. Each bus bar line has a distance between opposite ends thereof in the second direction smaller than a distance between outermost ones of the finger lines respectively disposed at opposite sides in the second direction.
