This study, direct
protonated nuclear prototypes which are reinforced with Pm-147 radioisotope. Open circuit voltage and short circuit
current of the developed betavoltaic nuclear cell were measured,
current-voltage curves were drawn, fill factor and efficiency values were
calculated. The total charge, saturation voltage, charge current and
capacitance accumulated on the directly charged nuclear battery prototype
developed were measured. The developed software analyzes the data depending on
the type and activity of the source used and automatically calculates the
maximum current-voltage, charging factor, short-circuit current, open-circuit
voltage and efficiency values of the battery. Pm-147
radioactive thin film production studies were conducted. On the other hand, the
optimum thin film thickness is determined by MCNP simulation. For the obtained
thickness value, it is determined which ratio of the source and the ratio of
beta energy spectrum. Using the results obtained, the source was coated with
electrolysis method. The radioactive thin film prepared in the final stage were
matched with the semiconductor devices and the production of the betavoltaic
nuclear battery was completed. The produced prototypes were placed in a
suitable vacuum cell and current-voltage-power measurements were made under
vacuum.
