The inclusion of luminescent material in the ethylene vinyl acetate (EVA) encapsulation layer of multicrystalline silicon (mc-Si) photovoltaic modules offers a production-ready method for the improvement of their short-wavelength (λ) spectral response and overall conversion efficiency. Several luminescent materials and mixtures thereof were evaluated for this purpose in an EVA matrix, including perylene and violanthrone dyes and a novel ligand sensitised europium complex. The external quantum efficiency of mc-Si modules can be greatly improved in the region of 300 nm <; λ <; 400 nm via luminescent down-shifting (LDS) of the incident light. In the best-case scenario, an increase in efficiency of 0.3% absolute is reported for a 59-cm2 minimodule. The LDS technology cannot only be simply transferred to a standard production line with no added layers and/or manufacturing processes but can be used to color photovoltaic (PV) modules for architectural purposes as well.
