Wide excitation spectra by Nd3+/Pr3+/Yb3+ doped phosphate glass for mono-crystalline silicon cells

Abstract We prepared Nd 3+ /Pr 3+ /Yb 3+ tri-doped phosphate glass by high-temperature melting method. The glass can efficiently transfer the sunlight into the near-infrared luminescence (∼1000 nm). Which can be applied to the spectrum converter of the solar battery of crystalline silicon. It is hopeful for improving the efficiency of solar battery.
