H10F 10/16

Photovoltaic cells having only PN heterojunction potential barriers

Introduced: January 2025

Full Title

Full titles differ between systems:

IPC:

Individual photovoltaic cells, e.g. solar cells > having potential barriers > Photovoltaic cells having only PN heterojunction potential barriers

CPC:

Individual photovoltaic cells, e.g. solar cells (electrolytic light-sensitive devices, e.g. dye-sensitised solar cells, H01G9/20) > having potential barriers > Photovoltaic cells having only PN heterojunction potential barriers

Of 6 combined children, 5 exist in both systems.

1 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2025.
