  7. Abstract:
  8. Nuclear batteries have been attractive since the beginning of the twentieth century due to their longer life in comparison with other types of batteries. These batteries are produced in different types with different efficiencies depending on the method used to convert their energy. In this study, due to the lack of the resources in the country to study the types of nuclear batteries, first we did an overview of the classification and operation of different types of nuclear batteries, especially on the latest type of nuclear batteries, PIDEC, that has not been studied in the country so far. The most important feature of a PIDEC is that it has an intermediate stage to transmit the maximum amount of radioactive material energy compared to other types of nuclear batteries. The simulation of this battery including excimer material and photovoltaic cell was performed using Geant4 and the factors affecting its efficiency such as geometric shape, dimensions, temperature, and pressure were evaluated. The results show that a PIDEC with Kr-85 as a source, Kr2 as an excimer, and diamond as a photovoltaic cell gives the best efficiency among studied models
