      abstract     = {Photoluminescence spectroscopy is a widely applied
                      characterization technique for semiconductor materials in
                      general and halide perovskite solar cell materials in
                      particular. It can give direct information on the
                      recombination kinetics and processes as well as the internal
                      electrochemical potential of free charge carriers in single
                      semiconductor layers, layer stacks with transport layers,
                      and complete solar cells. The correct evaluation and
                      interpretation of photoluminescence requires the
                      consideration of proper excitation conditions, calibration
                      and application of the appropriate approximations to the
                      rather complex theory, which includes radiative
                      recombination, non‐radiative recombination, interface
                      recombination, charge transfer, and photon recycling. In
                      this article, an overview is given of the theory and
                      application to specific halide perovskite compositions,
                      illustrating the variables that should be considered when
                      applying photoluminescence analysis in these materials.},
