To provide a solar cell preventing a side leakage without forming an isolation trench increasing an ineffective area by a connecting section between photoelectric conversion layers and increasing a laser machining process.
The solar cell has a power generation unit with at least two layers of the laminated photoelectric conversion layers 4 and 8 and intermediate regions 15 and 25 being interposed between the two layers of the photoelectric conversion layers 4 and 8 and electrically and optically connecting two layers of these photoelectric conversion layers. In the solar cell, the intermediate regions contain small regions 16 and 26 electrically dispersed discontinuously in the extension direction of two layers of the photoelectric conversion layers. Such a solar cell is provided.
