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 solar cell, comprising:
a photovoltaic structure; and a first electrode positioned on a first side of the photovoltaic structure,
wherein the first electrode comprises one or more finger lines,wherein an end of a respective finger line is coupled to a corresponding end of an adjacent finger line via a connecting metal line, andwherein a portion of the respective finger line that is in the vicinity of the coupled end is wider than a center portion of the respective finger line.
