ABSTRACT:
In the fabrication processes of a solar cell, a first p-n junction having the function of supplying electric power to the exterior of the solar cell is formed in the vicinity of the light receiving surface, while a second p-n junction is provided in a position separated from the light receiving surface. The two p-n junctions are interconnected in anti-parallel, so that, when a reverse voltage is applied to the first p-n junction, the second p-n junction is forward biased to permit current flow therein, thereby preventing the solar cell from breaking down. Since the first and second p-n junctions are integrated with each other, the cost of fabricating the solar cell is decreased and the reliability thereof is improved.
