A novel broadband sensitized near-infrared emitting phosphor, Eu2SiS4:Er3+, was developed as promising solar spectral converter for Si solar cells. Eu2SiS4:Er3+ has broadband absorptions ranging from 250 nm to 550 nm which can efficiently facilitate the UV-green part of the solar photon flux spectrum and exhibits intense NIR emission of Er3+, perfectly matching the maximum spectral response of Si solar cells. The NIR integrated emission intensity of Eu2SiS4:0.02Er(3+) is 6.14 times as intense as that of a dual-mode solar spectral converter CaLaGa3S6O:0.01Ce(3+), 0.06Pr(3+). These results demonstrate that Eu2SiS4:Er3+ phosphor is a promising candidate used as solar spectral converter.
