If only they defined what they meant by 'output' in the title to make it less sensational. Most readers will likely interpret this as energy, which is not the case. The author meant output of electrons per photon absorbed. (The breakthrough is that high energy photons can be absorbed with less loss of energy by converting them into multiple electrons.)
