ADE enabling TOPCON cells

ADE used successfully to fully remove the wrap around poly-silicon (poly-Si) in TOPCON cells.

The single sided nature and versatility of the ADE etching process makes it ideal to use for the removal of the parasitic poly-silicon layer deposited during the deposition process.

Results with several partners have shown excellent removal of the poly-Si from both the top wafer surface, and more crucially from the wafers edges, where any remaining poly-Si would create shunting and would result in irreversible hot spot damage of the cell when used inside a module. Module reliability is critical. The ADE process is an enabling step for the development of reliable TOPCON solar cell technology.
