A research team at the Daegu Gyeongbuk Institute of Science and Technology (DGIST), South Korea, has achieved a 56,000-fold increase in electron mobility by developing a novel betavoltaic cell that integrates a perovskite absorber layer with a radioactive isotope electrode.
This marks the creation of the world’s first next-generation betavoltaic cell, which promises stable, high-efficiency power generation for decades without recharging.
“This research marks the world’s first demonstration of the practical viability of betavoltaic cells,” said Professor Su-Il In, who led the team.
