Alpha voltaic batteries and methods thereof

A method for generating power, the method comprising:

• emitting alpha particles from an alpha particle emitter into at least one absorption and conversion area, the absorption and conversion area comprises one of a rare earth oxide, a rare earth doped garnet crystal, and quantum dots;
• preventing at least a portion of the emitted alpha particles from the at least one alpha particle emitter from damaging at least one p/n junction in at least one semiconductor material with the absorption and conversion area;
• and
• converting at least a portion of energy from the alpha particles into electron-hole pairs for collection by the at least one p/n junction in the at least one semiconductor material.

A method for generating power, the method comprising:

• emitting alpha particles from an alpha particle emitter into at least one absorption and conversion area on at least one semiconductor material;
• preventing at least a portion of the emitted alpha particles from the at least one alpha particle emitter from damaging at least one p/n junction in the at least one semiconductor material with the absorption and conversion area;
• and
• fluorescing photons in the at least one absorption and conversion area in response to at least a portion of energy from the alpha particles into electron-hole pairs for collection by the at least one p/n junction in the at least one semiconductor material.
