Abstract:
A power source comprises at least one photovoltaic cell arranged adjacent a plurality of self-luminous microspheres containing a radioactive material such as tritium and phosphor particles. Photons generated from the phosphor particles strike the photovoltaic array which converts the light to electrical energy. The self-luminous microspheres can be arranged adjacent the photovoltaic array using a binder material. The inventive power source provides a portable, safe, and long lasting battery which is adaptable for a wide range of applications requiring a reliable power source.
