Abstract
A betavoltaic power source. The power source comprises a source of beta particles and a plurality of regions each for collecting the beta particles and for generating electron hole pairs responsive to the beta particle flux. A first set of the plurality of regions is disposed proximate a first surface of the source and a second set of the plurality of regions is disposed proximate a second surface. The first and second surface in opposing relation. A secondary power source is charged by a current developed by the electron hole pairs.
Claims21
A betavoltaic power source comprising:
- a source of beta particles;
- a plurality of regions each for collecting the beta particles and for generating electron hole pairs responsive thereto, a first set of the plurality of regions disposed proximate a first surface of the source and a second set of the plurality of regions disposed proximate a second surface, the first and second surface in opposing relation;
- and
- a secondary power source charged by a current developed by the electron hole pairs.
A betavoltaic power source comprising
- first and second spaced-apart sources for emitting beta particles;
- first and second collecting regions for collecting the beta particles from the respective first and second tritium and for generating electron hole pairs responsive thereto, the collecting regions disposed between the first and second tritium sources;
- and a secondary power source charged by a current developed by the electron hole pair.
A betavoltaic power source comprising:
- a source of beta particles;
- a plurality of regions each for collecting the beta particles and for generating electron hole pairs responsive thereto, a first set of the plurality of regions disposed proximate a first surface of the source and a second set of the plurality of regions disposed proximate a second surface, the first and second surface in opposing relation;
- the plurality of regions electrically connected in a parallel electrical connection, a series electrical connection, or a series/parallel electrical connection, and
- a secondary power source charged by a current developed by the electron hole pairs.
