Efficient Luminescent Solar Concentrators Based on Defectless Organic Glasses Containing Novel Ytterbium Cyanoporphyrazine Complex

A photocurable polymeric luminescent composition doped by a new ytterbium tetra(4-fluorophenyl)tetracyanoporphyrazine complex capable of efficiently absorbing and reemitting light in a wide spectral range is developed. Defect-free organic glasses obtained with the use of this composition were applied as waveguides in the creation of laboratory models of a luminescent solar concentrator. Tests results of the created models showed the possibility of creating a stationary solar energy concentrator for photovoltaic cells (PVCs) which is at least as efficient as the best kinds of similar devices previously found worldwide.
