Abrégé
(EN) Disclosed is a spherical compound semiconductor cell wherein a compound semiconductor film that can suppress recombination and a leak current is sued. The spherical compound semiconductor cell is provided with: a spherical electrode (1), having at least the surface thereof formed of a conductor; a compound semiconductor layer (2), which is formed on the surface of the spherical electrode (1), and which has a chalcopyrite structure; buffer layers (3, 4) formed on the surface of the compound semiconductor layer (2); and a transparent electrode layer (5) formed on the surfaces of the buffer layers (3, 4). In the spherical compound semiconductor cell, recombination and a leak current are suppressed, and photoelectric conversion efficiency is increased by having the cell structure provided with the buffer layers (3, 4).
