Photovoltaic devices with electroplated metal grids

摘要

One embodiment of the present invention provides a solar cell. The solar cell includes a photovoltaic structure and a front-side metal grid situated above the photovoltaic structure. The front-side metal grid also includes one or more electroplated metal layers. The front-side metal grid includes one or more finger lines, and each end of a respective finger line is coupled to a corresponding end of an adjacent finger line via an additional metal line, thus ensuring that the respective finger line has no open end.

主权项

1. A metallic grid positioned on a photovoltaic structure, the metallic grid comprising:
a first finger line positioned on a first surface of the photovoltaic structure; a second finger line positioned on the first surface of the photovoltaic structure, wherein the second finger line is substantially parallel to the first finger line; and a metallic line connecting an end of the first finger line to an adjacent end of the second finger line; wherein a portion of the first finger line in a vicinity of an intersection between the first finger line and the metallic line is wider than a center portion of the first finger line.
