                      shown to be critical for perovskite device performance.
                      However, quantitative characterization of interface
                      recombination has so far proven to be highly challenging in
                      working perovskite solar cells. Here, methylammonium lead
                      halide (CH3NH3PbI3) perovskite solar cells are studied based
                      on a range of different hole‐transport layers, namely, an
                      inorganic hole‐transport layer CuOx, an organic
                      hole‐transport layer poly(triarylamine) (PTAA), and a
                      bilayer of CuOx/PTAA. The cells are completed by a
                      [6,6]‐phenyl‐C61‐butyric acid methyl ester
                      (PCBM)/bathocuproine/Ag electron contact. Energy levels are
                      characterized using photoelectron spectroscopy and
                      recombination dynamics by combining steady‐state
                      photoluminescence and transient photoluminescence with
                      numerical simulations. While the PTAA‐based devices hardly
                      show any interface recombination losses and open‐circuit
                      voltages >1.2 V, substantial losses are observed for the
                      samples with a direct CuOx/perovskite interface. These
                      losses are assigned to a combination of energetic
                      misalignment at the CuOx/perovskite interface coupled with
                      increased interface recombination velocities at the
                      perovskite/PCBM interface.},
