This solar cell is provided with: at least one light absorption section (13) that generates a light-generated carrier by absorbing light
and at least one direction-changing layer (12) that changes the direction in which light travels along the main surface (13p) of the light absorption section (13). The direction-changing layer (12) changes the direction in which light travels by converting light that is incident on the direction-changing layer (12) into light having a phase change on the wavefront in the direction along the main surface (13p) of the light absorption section (13).
