Simulation of the Parameters of a Titanium-Tritide-Based Beta-Voltaic Cell

Аннотация

The simulation of β-voltaic power cells consisting of a combined β-source and a converter was performed. The TiT₂ compound containing the radioactive tritium isotope was selected as the source. As the converter, structures based on semiconductor materials, most commonly used in developing power cells, i.e., Si, SiC, GaAs, were considered. Using the Monte Carlo method, the main source parameters were calculated, in particular, the maximum achievable short-circuit current was estimated.
