DIFF Subgroup
H10F 10/10 having potential barriers
Introduced: January 2025
Full Title
Full titles differ between systems:
IPC:
Individual photovoltaic cells, e.g. solar cells > having 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
IPC and CPC are identically structured here. All 8 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2025.
