High Resolution Image Download MS PowerPoint Slide Downshifters refer to compounds with the capacity to absorb UV photons and transform them into visible light. The integration of such downshifters has the potential to improve the efficiency of commercial photovoltaic modules. Initially, costly lanthanide derivatives and organic fluorescent dyes were introduced, resulting in a heightened module efficiency. In a novel research direction guided by the same physicochemical principles, the utilization of copper(I) coordination compounds is proposed. This choice is motivated by its simpler and more economical synthesis, primarily due to copper being a more abundant and less toxic element. Our proposal involves employing 1,2-bis(4-pyridyl) ethane ( bpe ), an economically viable commercial ligand, in conjunction with CuI to synthesize coordination polymers: [CuI(bpe)] n (1), [Cu 3 I 3 (bpe) 3 ] n (2), and [CuI(bpe) 0.5 ] n (3) . These polymers exhibit the ability to absorb UV photons and emit light within the green and orange spectra. To conduct external quantum efficiency studies, the compounds are dispersed on glass and then encapsulated with ethylene vinyl acetate through heating to 150 °C. Interestingly, during these procedural steps, the solvents and temperatures employed induce a phase transformation, which has been thoroughly examined through both experimental analysis and theoretical calculations. The outcomes of these studies reveal an enhancement in external quantum efficiency with [Cu 3 I 3 (bpe) 3 ] n ( 2 ), at a cost significantly lower (between 340 and 350 times) than that associated with lanthanide DS complexes.
