Abstract
A power converter comprises a first die and a second die. Each die comprises a semiconductor substrate comprising a junction for converting nuclear radiation particles to electrical energy, the junction of each semiconductor substrate comprising a first side and a second side, a first electrode comprising a nuclear radiation-emitting radioisotope deposited on the semiconductor substrate, the first electrode being electrically connected to the first side of the junction, and a second electrode deposited on the semiconductor substrate, the second electrode being electrically connected to the second side. A bond is formed between one of the first electrode or the second electrode of the first die and one of the first electrode or the second electrode of the second die, wherein the bond forms an electrical contact between the bonded electrodes.
