Comparison of FC systems depicted in Figures 1b and 1c with a constant coverage fraction f = 0.01 analyzing influence of non-radiative losses in the dye. (a) Side-mounted system is only modeled up to a collector length l ≤ l_max = 4d/f corresponding to a full coverage of all collector sides. Inclusion of non-radiative losses deteriorates the photon collection p_c in all cases. The effect is more significant in the system with applied PBS. (b) Bottom-mounted system. The simulation covers a wider range of collector lengths. With PBS the bottommounted system in its radiative limit shows a significant drop in p_c for l/d ≥ 100. The inclusion of non-radiative losses reduces this limit to l/d ≥ 1. In comparison : for p_nr = 0 (only radiative losses) the side-mounted system leads to a better photon collection p_c, especially at large values of l. Inclusion of non-radiative losses leads to the same behavior in the largescale region, but for collector lengths in the statistical limit, the bottom-mounted system performs better. Without PBS the side-mounted system yields higher p_c at all collector lengths even with inclusion of non-radiative losses.
