Multiple exciton generation boosting over 100% quantum efficiency photoelectrochemical photodetection

Xue et al. report self-powered photoelectrochemical photodetectors based on CuOx decorated AlGaN nanowires with staggered energy band structure. High-energy photons can be absorbed by CuOx to trigger the multiexciton generation effect, enabling an external quantum efficiency of 131.5% at 255 nm.
