  Light Management (LM) is essential for metal-halide perovskite solar cells in
their race for record performance. In this review, criteria on materials,
processes and photonic engineering are established such as to enhance mainly
the short circuit current density, towards high energy yields. These criteria
are used to analyse a large panel of solutions envisaged in the literature for
single junction cells. Moreover, a perspective based on rigorous
electromagnetic simulations performed on various comparable structures is
proposed in order to clarify the conclusions, and to pave the way to further
performance enhancement in the case of all-perovskite, two-terminal tandem
cells.
