A prototype betavoltaic battery announced in early 2024 by the Betavolt company of China contains a thin wafer providing a source of beta particle electrons (either Carbon-14 or nickel-63) sandwiched between two thin crystallographic diamond semiconductor layers.
The Chinese startup Betavolt claimed in January 2024 to have a miniature device in the pilot testing stage. [13] It is allegedly generating 100 microwatts of power and a voltage of 3V and has a lifetime of 50 years without any need for charging or maintenance. [13] Betavolt claims it to be the first such miniaturised device ever developed. [13]
Betacel is considered to be the first commercially successful betavoltaic battery. [1] [2] [3] It was developed in the early 1970s by Larry C. Olsen at the American corporation McDonnell Douglas, using the radioisotope Promethium-147 as the beta-electron source coupled to silicon semiconductor cells.

The company had only $30 million of cash at the time of the filing, enough to sustain it for one week, while its debts stood at $5.8 billion, including $313 million owed to the European Investment ...
In September 2020, Morgan Boardman, an Industrial Fellow and Strategic Advisory Consultant with the Aspire Diamond Group at the South West Nuclear Hub of the University of Bristol, was appointed CEO of a new company called Arkenlight, which was created explicitly to commercialize their diamond battery technology and possibly other nuclear ...
An optoelectric nuclear battery [citation needed] (also radiophotovoltaic device, radioluminescent nuclear battery [1] or radioisotope photovoltaic generator [2]) is a type of nuclear battery in which nuclear energy is converted into light, which is then used to generate electrical energy.
