Abstract
Provided is a solar cell with improved photoelectric conversion efficiency. The solar cell includes a photoelectric conversion body and first and second electrodes. The photoelectric conversion body includes a substrate made of semiconductor material. The first and second electrodes are disposed at intervals on one main surface of the photoelectric conversion body. Terraces each formed of a crystal plane are provided on a main surface of the substrate on the one main surface side of the photoelectric conversion body. At least one of the terraces exists between the first electrode and the second electrode.
