AbstractCe3+-Yb3+ doped Y3Al5O12 (YAG) is a luminescent down-conversion material which could convert visible pho- tons to near infrared photons. In this work, YAG:Ce3+-Yb3+ is applied on the front surface of mass-produced mono crystalline Si solar cells. For the coated cells, the external quantum efficiencv from the visible to the near infrared is improved, and the energy conversion efficiency enhances from 11.70% to 12.2% under AMI.SG. Furthermore, the phosphor down-conversion effect on the solar cell is characterized by the microwave detected photoconductivity technique on the n-type silicon wafer under the 977nm excitation. The down-conversion materials improve the average excess carrier lifetime from 22.5μs to 24.2#s and the average surface recombi- nation velocity reduces from 424.Scm/s to 371.6cm/s, which reveal the significant reduction in excess carrier recombination by the phosphors.
