Abstract
A solar cell element comprises a semiconductor substrate, a passivation layer, and first to third electrodes. The passivation layer with first holes is located on the semiconductor substrate. The first electrode is located in each of the first holes and electrically connected to the semiconductor substrate. The second electrode is electrically connected to the first electrode and located on the passivation layer. The third electrodes is electrically connected to the first electrode via the second electrode. The passivation layer includes a part where a ratio of an area occupied by the first holes in a first region adjacent to the third electrodes is smaller than a ratio of an area occupied by the first holes in a second region located farther away from the third electrodes in relation to the first region and having an area equal to an area of the first region in a perspective plan view.
