Photovoltaic structures with interlocking busbars
First Claim
1. A photovoltaic structure, comprising:
- a first metallic grid positioned on a first surface of the photovoltaic structure, wherein the first metallic grid includes a first set of discontinuous segments positioned near an edge of the photovoltaic structure; and
a second metallic grid positioned on a second surface of the photovoltaic structure, wherein the second metallic grid includes a second set of discontinuous segments positioned near an opposite edge of the photovoltaic structure;
wherein the first and the second sets of discontinuous segments have substantially complementary topology profiles such that, when the edge of the photovoltaic structure overlaps with an opposite edge of an adjacent photovoltaic structure with a same metallic-grid configuration, a respective segment on the first surface of the photovoltaic structure fits in a corresponding gap between two neighboring segments on the second surface of the adjacent photovoltaic structure, thereby facilitating interlocking of the segments between the two photovoltaic structures wherein, within each of the first and second metallic grids, the discontinuous segments are not directly coupled to one another by a metallic material except by segments of another grid when two photovoltaic structures are overlapped.

Abstract
One embodiment can provide a current-collecting mechanism of a photovoltaic structure. The current-collecting mechanism can include a top metallic grid positioned on a top surface of the photovoltaic structure and a bottom metallic grid positioned on the bottom surface of the photovoltaic structure. The top metallic grid can include a top busbar positioned near an edge of the photovoltaic structure, and the bottom metallic grid can include a bottom busbar positioned near an opposite edge. The top busbar and the bottom busbar can have complementary topology profiles such that, when the edge of the photovoltaic structure overlaps with an opposite edge of an adjacent photovoltaic structure, the top busbar of the photovoltaic structure and the bottom busbar of the adjacent photovoltaic structure interlock with each other.
