Light Management in Perovskite Photovoltaic Solar Cells: A Perspective

Light management is essential for metal‐halide perovskite solar cells to achieve record performance. In this review, criteria on materials, processes, and photonic engineering are established to enhance primarily the short circuit current density for high energy yields. These criteria are used to analyze a large panel of solutions envisaged in the literature for single junction cells. In addition, a perspective acquired from rigorous electromagnetic simulations performed on various comparable structures is introduced to clarify the results of the analyses and to pave the way for further performance enhancement in the case of all‐perovskite, two‐terminal tandem cells.
