  • Solar cell and method of manufacturing same
    Publication number: 20020104562
    Abstract: A solar cell is manufactured by bringing a front side of a semiconductor crystal substrate into contact with an electrolytic liquid containing a fluoride, placing an electrode in the electrolytic liquid, passing a current between the electrode and the semiconductor crystal substrate and applying light to the semiconductor crystal substrate to generate pairs of holes and electrons. Etching of the substrate proceeds by combining the holes with ions in the front side of the semiconductor crystal substrate which is held in contact with the electrolytic liquid, thereby forming at least one surface irregularity structure thereon.
