  1. Mean and standard deviation of photovoltaic device parameters for 6 as-cast devices on the same substrate with the following active layer compositions: Binary (B1): PM6:Y6 (1:1.2); Ternary (T1): PM6:Y1:Y18 (1:0.6:0.6); Quaternary (Q1): PM6:Y6:Y11:Y16 (1:0.4:0.4:0.4); Pentanary (P1): PM6:Y1:Y6:Y11:Y16 (1:0.3:0.3:0.3:0.3); Hexanary-1 (H1): PM6:Y1:Y6:Y11:Y16:Y18 (1:0.24:0.24:0.24:0.24:0.24) and Hexanary-5 (H5): PM6:Y6:Y7:Y18:N3:BTP-eC9 (1:0.24:0.24:0.24:0.24:0.24). The donor:acceptor ratios are given as weight ratios.
