<p>A method for producing a solar cell which uses a CZ silicon single crystal wafer, characterized in that a CZ silicon single crystal wafer having an initial interstitial oxygen concentration of 15 ppma or less is used as the CZ silicon single crystal wafer; a solar cell which is manufactured with a CZ silicon single crystal wafer, characterized in that the CZ silicon single crystal wafer has an initial interstitial oxygen concentration of 15 ppma or less; and a solar cell which is manufactured with a CZ silicon single crystal wafer, characterized in that the CZ silicon single crystal wafer has a BMD density of 5 x 108/cm3 or less. The solar cell is advantageous in that it exhibits a reduced range of the variation of properties.</p> |
