Bridging solar cell and solar energy system

摘要

A bridging solar cell includes a substrate, first, second, and third sets of bus bar electrodes, a first welding member, a first insulation film, and a second welding member. The first set of bus bar electrodes is disposed on the front surface of the substrate along a first direction. The second set of bus bar electrodes is disposed on the back surface of the substrate along a second direction and electrically connected to the first set of bus bar electrodes. The first welding member is electrically connected to the second set of bus bar electrodes. The first insulation film is disposed on the back surface. The third set of bus bar electrodes is disposed on the first insulation film along the second direction. The second welding member is disposed on the first insulation film and electrically connected to the third set of bus bar electrodes.

主权项

1. A bridging solar cell comprising:
a substrate having a front surface and a back surface; a first set of bus bar electrodes disposed on the front surface and extending along a first direction; a second set of bus bar electrodes disposed on the back surface and extending along a second direction different from the first direction and electrically connected to the first set of bus bar electrodes via the substrate; a first insulation film disposed on the back surface between a portion of the second set of bus bar electrodes and the back surface; a first welding member disposed on the first insulation film and electrically connected to the second set of bus bar electrodes; a third set of bus bar electrodes disposed on the first insulation film and extending along the second direction so as to be insulated from the substrate; and a second welding member disposed on the first insulation film and electrically connected to the third set of bus bar electrodes.
