While cuprous oxide is a promising solar-to-fuel conversion material, photoelectrochemical devices substantially underperform. Here, the authors use femtosecond time-resolved two-photon photoemission spectroscopy to correlate photoexcited electron en

The theoretical maximum efficiency of a solar cell is given by the Shockley-Queisser limit, which assumes an abrupt onset of absorption near the band-edge. However, real materials always have an imperfect band-edge, which is usually characterized by
