CIGS COMPOUND SOLAR CELL |
摘要 |
In order to provide a CIGS compound solar cell with a high conversion efficiency, a CIGS compound solar cell including a rear electrode layer, a CIGS light absorbing layer, a buffer layer, and a transparent electrode layer in this order over a substrate is configured such that the buffer layer comprises a mixed crystal of a Group IIa metal and zinc oxide, and characteristics of the mixed crystal as shown by X-ray diffraction satisfy the following formula (1):;0.5≦A/(A+B+C)<1 (1);(where none of A, B, C are 0)
A: peak intensity at plane (002)B: peak intensity at plane (100)C: peak intensity at plane (101). |
