Researchers at Suzhou University (Li Yaowen, Chen Xiankai) and Southeast University (Zhang Tiankai) proposed an 'electronic resonance' strategy to address low efficiency and poor stability in flexible perovskite photovoltaic cells. The results were published online in Nature on the 22nd. The team describes perovskite PV as a next‑generation, lightweight, thin and flexible technology with applications from space-station and deep‑space base power to clothing- and skin-mounted devices that can generate electricity wherever sunlight is available.
