Yb~(3+)/Er~(3+)co-doped Na_5Lu_9F_(32) single crystals used as a spectral up-converter to improve the power conversion efficiency of perovskite solar cells are prepared via an improved Bridgman approach. Green and red up-conversion(UC) emissions under the excitation of near-infrared(NIR) bands of 900–1000 nm and1400–1600 nm can be observed. The effectiveness of the prepared materials as a spectral converter is verified by the enhancement of power conversion efficiency of perovskite solar cells. The sample with a UC layer is 15.5%more efficient in converting sunlight to electricity compared to the UC layer-free sample due to the absorption of sunlight in the NIR range. The results suggest the synthesized Yb~(3+)/Er~(3+)co-doped Na_5Lu_9F_(32) single crystals are suitable for enhancing the performance of perovskite solar cells. 相似文献

Possible structures and properties of some excited states of Λc+ dynamically generated in the coupled-channel P-wave meson-baryon scattering are studied by solving the Bethe-Salpeter(BS) equation in the framework of the Chiral Unitary Approach. It is shown that both Λc+(2765) and Λc+(2940) could be generated dynamically and could be compound states with multi-configuration molecular-like structures. The couplings of the generated states to various reaction channels are also calculated. Moreover, two highly excited states, Λc+(3024) and Λc+(3134), are predicted. 相似文献
