OPTOELECTRIC CONVERSION ELEMENT AND ITS MANUFACTURING METHOD, AND OPTOELECTRIC CONVERSION MODULE USING SAME |
摘要 |
<p>A photovoltaic conversion element includes a one conductivity-type crystalline Si semiconductor; an opposite conductivity-type semiconductor which is joined to the crystalline Si semiconductor to form a pn junction therebetween; an electrode provided on the opposite conductivity-type semiconductor; and a depletion region formed from the side of the one conductivity-type crystalline Si semiconductor to the side of the opposite conductivity-type semiconductor across the pn junction formed therebetween. The depletion region has a first depletion region located inside the crystalline Si semiconductor and under the electrode, and the first depletion region has an oxygen concentration of 1E18 [atoms/cm 3 ] or less.</p> |
