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.
