• G21H 1/02 Cells charged directly by beta radiation
• G21H 1/04 Cells using secondary emission induced by alpha radiation, beta radiation, or gamma radiation
• G21H 1/06 Cells wherein radiation is applied to the junction of different semiconductor materials
• G21H 1/08 Cells in which radiation ionises a gas in the presence of a junction of two dissimilar metals, i.e. contact potential difference cells
• G21H 1/10 Cells in which radiation heats a thermoelectric junction or a thermionic converter
• G21H 1/12 Cells using conversion of the radiation into light combined with subsequent photoelectric conversion into electric energy
