<p><P>PROBLEM TO BE SOLVED: To provide a highly efficient solar cell with high production yield, in which shielding of sunlight by an electrode on a surface of a substrate is small and peeling of the electrode due to acid immersion can be prevented. <P>SOLUTION: The solar cell is provided with the semiconductor substrate 1 where PN-junction is formed, a finger electrode 2 which is formed on at least one face of the semiconductor substrate 1 in a comb teeth shape and a bus bar electrode 3 connected to the finger electrode 2. The finger electrode 2 is provided with a constant width part 4 where electrode width connected to the bus bar electrode 3 is constant and a wide width part 5 which is connected to the constant width part 4 and whose width is wider than the constant width part 4. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
