Claims

What is claimed is:

1. A method of manufacturing photovoltaic modules, the method comprising the steps of:

advancing a plurality of photovoltaic cells, wherein the cells include electrolyte; and

ultrasonically dividing a subset of the plurality of photovoltaic cells into one or more photovoltaic modules,

wherein the dividing step includes concurrently cutting and sealing the subset of photovoltaic cells into one or more photovoltaic modules and the sealing helps prevent leakage of electrolyte.

2. The method of claim 1, wherein the plurality of photovoltaic cells comprises a continuous flexible sheet of photovoltaic cells.

3. The method of claim 1, wherein the advancing step is performed as part of a continuous manufacturing process.

4. The method of claim 3, wherein the continuous manufacturing process comprises a roll-based process.

5. The method of claim 1, wherein the plurality of photovoltaic cells is flexible.

6. The method of claim 1, wherein cutting and sealing forms a leading edge on a proximal portion of the one or more photovoltaic modules.

7. The method of claim 1, wherein cutting and sealing forms a trailing edge on a distal portion of the one or more photovoltaic modules.

8. The method of claim 1, wherein the sealing prevents the electrolyte from leaking.

9. The method of claim 1, wherein the dividing step interrupts at least one conductive layer of the photovoltaic cells.
