Maps of the short-circuit current (a) and total reflectance (b) in terms of the index of refraction of the dimer’s material and the lateral size, GW, of the cuboid element. The reflectance of the whole device, R, is calculated in the range \(\lambda \in [300, 800]\) nm. The dashed curves define three regions in performance.
