PROBLEM TO BE SOLVED: To provide a solar cell and a solar cell panel including the same, capable of improving the output and reliability of the solar cell panel.SOLUTION: A solar cell according to the present embodiment includes a semiconductor substrate having a chamfer formed at an edge thereof and an electrode electrically connected to the semiconductor substrate through a conductivity type region. The electrode includes a plurality of finger lines extending in a first direction, and a plurality of bus bars positioned in a second direction intersecting the first direction and connecting the plurality of finger lines. The plurality of bus bars include a pair of first bus bars respectively positioned at opposite ends of the semiconductor substrate and separated in the first direction by a first width greater than a width of the chamfer, and a second bus bar positioned between the first bus bars. The plurality of finger lines in a first area between one end of the semiconductor substrate and one of the first bus bars have different shapes from the plurality of finger lines in a second area between the pair of first bus bars.SELECTED DRAWING: Figure 7 【課題】太陽電池パネルの出力及び信頼性を向上できる太陽電池及びこれを含む太陽電池パネルを提供すること。【解決手段】本実施形態に係る太陽電池は、角に面取り（ｃｈａｍｆｅｒ）が形成された半導体基板と、導電型領域を介して前記半導体基板と電気的に接続される電極とを備え、前記電極は、第１の方向に伸びている複数のフィンガーラインと、前記第１の方向と交差する第２の方向に位置し、前記複数のフィンガーラインを連結する複数のバスバーとを備え、前記複数のバスバーは、前記第１の方向に前記半導体基板の両端で各々前記面取りの幅より広い第１の幅に離れた一対の第１のバスバーと、前記第１のバスバー間に位置する第２のバスバーとを備え、前記複数のフィンガーラインは、前記半導体基板の終端と前記第１のバスバーとの間の第１の領域と、前記一対の第１のバスバー間の第２の領域とで形状が異なる。【選択図】図７
