摘要For the purpose of improving conversion efficiency of solar cells by applying the effect of the wavelength conversion of rare earth ions, photo-luminescence and excitation spectrums of Ce3+−Tb3+ doped phosphate glass are investigated. Results show that incorporating Ce3+ ions to Tb3+−doped phosphate glass can greatly increase the absorption coefficient in the range 300-400 nm and then the energy transfer (ET) from Ce3+ to Tb3+ occurs. In addition, increasing Tb3+ concentration in Ce3+/Tb3+ co−doped phosphate glass can greatly enhance the ET efficiency and 545 nm emission intensity. This shows that Ce3+/Tb3+ co-doped phosphate glass would be a promising down-shifting material for enhancing the efficiency of solar cells.
