A luminescent solar concentrator (LSC) device is provided. The LSC device has an active layer including a modified luminophore having a polymethine component including a plurality of methine groups (=CH-)n, where n is an odd integer greater than 1. A hydrogen atom (H) of one of the plurality of methine groups is replaced by one of or, where A is selected from nitrogen (N), phosphorus (P), arsenic (As) and antimony (Sb) and D is selected from oxygen (O), sulfur (S), selenium (Se), and tellurium (Te), R1 and R2 are independently selected from H, aliphatic groups, and aromatic groups bound to A through a carbon atom, or R1 and R2 together form an alicyclic ring containing A, and R3 is selected from H, aliphatic groups, aromatic groups, and alicyclic groups bound to D through a carbon atom. |
