A research team led by Prof. Haisheng San of Xiamen University and Prof. Xin Li of the China Institute of Atomic Energy has developed a new class of 90Sr radio-photovoltaic cells (RPVC) that combine high power output with long-term durability. The innovation relies on a waveguide light concentration (WLC) structure, integrating multilayer-stacked GAGG:Ce scintillation waveguides with stron
