SOLAR CELL AND MANUFACTURING METHOD OF THE SAME |
摘要 |
<p>A method for manufacturing a solar cell, comprising steps of: a) providing a semiconductor substrate having a light-receiving side and a back side, wherein a passivation layer is formed on the back side; b) forming a silver conductor pattern on the back side of the semiconductor substrate; c) forming an aluminum conductor pattern on the back side of the semiconductor substrate, at least part of the aluminum conductor pattern being superimposed on at least part of the silver conductor pattern; and d) firing the silver conductor pattern and the aluminum conductor pattern at the same time, thereby forming an electric contact between the semiconductor substrate and the aluminum conductor pattern by way of fire through in a region where the silver conductor pattern and the aluminum conductor pattern are superimposed.</p> |
