ABSTRACT:
In the fabrication processes of a solar cell, a first p-n junction having a function required for 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 not reached by incident light. 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 have a current flow therein, thereby to prevent the solar cell from breaking down. Since the first and second p-n junctions are integrated with each other, the cost for fabricating the solar cell is decreased and the reliability thereof is increased.
