Summary:PROBLEM TO BE SOLVED: To provide a solar cell having high efficiency and reliability.SOLUTION: A solar cell includes a photoelectric conversion part, a first electrode and a second electrode for connection with the photoelectric conversion part. The first electrode includes a finger electrode including a plurality of finger electrode parts, and a bus bar electrode including at least one of a main part formed in a direction crossing the plurality of finger electrode parts, and a protrusion protruding from the main part. The protrusion is formed across more than one of the plurality of finger electrode parts. 【課題】本発明は、高い効率及び信頼性を有する太陽電池を提供しようとする。【解決手段】本発明の実施例に係る太陽電池は、光電変換部と、前記光電変換部に接続される第１電極及び第２電極と、を含む。前記第１電極は、複数のフィンガー電極部を含むフィンガー電極と、前記複数のフィンガー電極部と交差する方向に形成されるメイン部分及び前記メイン部分から突出する突出部分を少なくとも一つ含むバスバー電極とを含む。前記突出部分が、前記複数のフィンガー電極部のうち少なくとも２つ以上にわたって形成される。【選択図】図４
