ABSTRACT:
An electrical power source or power cell (10) includes a semiconductor material (12) having an N region (14), a P region (16) and a P-N junction (18). A radioactive source (24) associates with P-N junction (18) and emits energy or radioactive particles (26) into semiconductor material (12). In semiconductor material (12), electron-hole pairs are formed in N region (14) and P region (16) to cause electrical current to pass through P-N junction (18) and produce, therefrom, electrical power.
