采用溶胶-凝胶法制备了Eu ~（3+）掺杂的SiO_2薄膜，并将其用作晶体硅太阳电池正面的发光下移层，以提高电池的转换效率。在标准测试条件（AM 1.5，100 mW/cm ~ 2）下的测试表明，与纯二氧化硅薄膜的硅太阳能电池相比，含Eu ~（3+）的二氧化硅薄膜的硅太阳能电池的转换效率最大提高了9.5%。然而，不鼓励高Eu 3+浓度，因为浓度猝灭效应将降低太阳能电池的效率。
Eu3+ doped silica films have been prepared by sol–gel method and employed as luminescent down-shifting layer on the front side of a crystalline Si solar cell to improve their conversion efficiency. Measurements under standard test conditions (AM1.5, 100 mW/cm2) show the conversion efficiency of Si solar cell with silica film containing Eu3+ is improved 9.5% maximally as compared to the Si solar cell with pure silica film. However, high Eu3+ concentration is not encouraged because concentration quenching effect will decrease the efficiency of the solar cell.
