Betavoltaic cell with perovskite-radioactive isotope combo can power long-term applications

A research team has developed the world's first next-generation betavoltaic cell by directly connecting a radioactive isotope electrode to a perovskite absorber layer. By embedding carbon-14-based quantum dots into the electrode and enhancing the perovskite absorber layer's crystallinity, the team achieved both stable power output and high energy conversion efficiency.

Tiny nuclear battery could power devices for decades without recharging

A team of researchers in South Korea has developed a new type of tiny nuclear battery that could power devices for years—or even decades—without ever needing to be recharged. This next-generation energy source, known as a betavoltaic cell, combines radioactive materials with a special solar cell material called perovskite. The breakthrough could be a game-changer […] The post Tiny nuclear battery could power devices for decades without rechargin…
