(a) Layout of the planar configuration of the perovskite solar cells and placement of the LT structures, later adapted to generate magenta or green chromaticities (Section 2.3). (b)–(f) Schematics of the light-trapping structures simulated in this study with respective geometrical variables and simulation unit cells (red area): 1D linear grating lines, 2D crossed grating lines, circular nanopillars, domes and double checkerboards. As a side note, the length of the checkerboard is mentioned in most of the following results, rather than the pitch, for a clearer geometrical comparison to the pitch of the remaining structures.
