SOLAR CELL AND ITS MANUFACTURING METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To realize an efficient solar cell through a combination of a composition distribution with the highest efficiency and an optimized heterostructure by using a practical casting method as a base without using a complicated structure such as a tandem type. <P>SOLUTION: A solar cell is provided with a double-layer heterostructure of a substrate 10 comprising a polycrystal of plural elements having a non- uniform micro composition distribution and a deposit 20 formed by depositing to grow a thin film crystal on this substrate. <P>COPYRIGHT: (C)2003,JPO</p> |
