•Photo- and thermo-stable luminescent beads composed of Eu(III) complex.•The stability of the luminescent beads for industrial application was calculated to be ten years under air condition.•Energy conversion efficiency of silicon solar cells attached EVA films with Eu(hfa)3(TPPO)2-beads increased approximately 2%.
Photo- and thermo-stable luminescent beads composed of Eu(hfa)3(TPPO)2 (hfa: hexafluoroacetylacetonate, TPPO: triphenylphosphine oxide) and PMMA (polymethylmethacryrate), Eu(hfa)3(TPPO)2-beads, have been reported for improvement of energy conversion efficiency on silicon solar cell. The photophysical properties of Eu(hfa)3(TPPO)2 and compared Eu(tta)3(TPPO)2 (tta: trifluoromethyl- thienylacetylacetonate) are characterized by the emission quantum yield, the emission lifetime, the radiative and the non-radiative rate constants. Photo- and thermo-stability of the beads with Eu(III) complexes in EVA (Ethylene Vinyl Acetate) are estimated under UV irradiation (Xenon lamp: 60 W/m2) and highly temperature (120 °C). The stability of the Eu(hfa)3(TPPO)2-beads for industrial application was calculated to be ten years under air condition. Energy conversion efficiency of silicon solar cells attached EVA films with Eu(hfa)3(TPPO)2-beads increased approximately 2%(10% → 10.2%) compared with EVA films contained with UV absorber. Photo- and thermo-stable Eu(hfa)3(TPPO)2-beads for silicon solar cells are demonstrated for the first time.
