Abstract
In this bypass-function added solar cell, a plurality of island-like p regions, which is third regions, are formed at a boundary between a p-type region and an n-type region layer constituting a substrate so that the p regions project into the region and the region and are separated away from the surface of the substrate. Therefore, in this solar cell, unlike prior art counterparts, the insulating film for isolating the p regions and the n electrodes constituting the np diode from one another is no longer necessary, thus allowing a reduction in manufacturing cost. As a result, a bypass-function added solar cell with a bypass-diode function added thereto can be provided with low cost and by simple process.
