英文摘要	down-conversion is a feasible way to improve conversion efficiency of silicon solar cell. however, the width of excitation band for down-converter based on trivalent lanthanide ions is still not satisfying. here, we designed and fabricated a heterostructural down-converter composed of y2o3: [(tb3+-yb3+), li+] quantum cutting phosphor and znse. the znse phase was used to absorb the incident light with energy larger than its bandgap, and transfer the energy to tb3+-yb3+ quantum cutting couple. short-wavelength incident light was finally converted into a strong yb3+ emission at about 1000 nm, locating at the maximal spectral response of silicon solar cell. the excitation band of the down-conversion covers a wide region of 250-550 nm. benefiting from the energy match between znse bandgap and f-7(6) -> d-5(4) absorption of tb3+ ions, the bandwidth of down-conversion is almost maximized.
