Solar cell and its manufacturing method |
摘要 |
A solar cell includes a conductive substrate, and an insulating layer, a conducting layer and a semiconductor layer that are disposed on the substrate. A through hole is formed so as to penetrate the insulating layer and the conducting layer, and the through hole is filled with a semiconductor that composes the semiconductor layer. At least one element selected from the elements composing the conductive substrate diffuses into the semiconductor with which the through hole is filled.
