Optoelectric nuclear battery

An optoelectric nuclear battery[

photovoltaic
cell.

The technology was developed by researchers of the Kurchatov Institute in Moscow.[citation needed]

Description

A

ionized plasma consists of gases or gas mixtures (such as krypton, argon, and xenon) with excimer lines such that a considerable amount of the energy of the beta electrons is converted into this light. The surrounding walls contain photovoltaic layers with wide forbidden zones, such as diamond, which convert the optical energy generated from the radiation into electrical energy.[citation needed

A German patent

carbon fiber/epoxy, the power-to-weight ratio
is said to be comparable to an air-breathing engine with fuel tanks. The advantage of this design is that precision electrode assemblies are not needed, and most beta particles escape the finely-divided bulk material to contribute to the battery's net power.

Disadvantages

The inherent risk of failure is likely to limit this device to space-based applications, where the finely-divided radioisotope source is only removed from a safe transport medium and placed in the high-pressure gas after the device has left Earth orbit.[citation needed]

As a DIY project

A simple betaphotovoltaic nuclear battery can be constructed from readily-available tritium vials (tritium-filled glass tubes coated with a radioluminescent phosphor) and solar cells.[5][6][7] One design featuring 14 22.5x3mm tritium vials produced 1.23 microwatts at a maximum powerpoint of 1.6 volts.[5] Another design combined the battery with a capacitor to power a pocket calculator for up to one minute at a time.[8]
