“…For a multilayer the phase shift can be calculated from electromagnetic theory by one of several methods. An accurate method employs multiplication of matrices, each matrix representing a single layer [ 26 , 27 ]. An exhaustive treatment of the subject has been given by Abelès [ 28 ], but the outline given by Koehler [ 29 ] is adequate for many problems.…”

In this work microcavity-capped colour-tuneable SMOSCs are evaluated. By adopting a microcavity-structured cathode with optical spacer layers of different thicknesses fabricated in a Ag/NPB/Ag structure, the transmission spectra of complete devices can be tuned over the entire visible-light region (400-750 nm). The fabricated semitransparent colour-tuneable solar cells show an average efficiency of 4.78% under 1-sun illumination.
