More importantly, addition further enhance photoelectric device, realizing an optimal 10.58%, one highest reported efficiencies UCNP-based with common N719 photosensitizer. Such remarkable improvement mainly due synergetic effect absorbing near-infrared light excellent potency. Specifically, steady-state experiments reveal best-performing device shows only small loss after 120 h testing, exhibiting good stability.
