采用均匀沉淀法制备了Gd 2 O3：Eu 3+下转换发光粉。分析了其光学性质，并将其应用于染料敏化太阳能电池（DSSC）。作为发光介质，Gd 2 O3：Eu 3+通过转换发光提高了DSSC的光捕获能力，增加了DSSC的光电流。作为p型掺杂剂，稀土氧化物形成能垒，Gd_2 O_3：Eu ~（3+）提高了氧化膜的能级，提高了光电压。掺杂Gd 2 O3：Eu 3+（6：100）的DSSC的光电转换效率达到7.01%，比未掺杂的DSSC的光电转换效率提高了17.4%。
Gd2O3:Eu3+ downconversion luminescent powder was prepared using the homogeneous precipitation method. Its optical properties were analyzed and it was introduced into a dye-sensitized solar cell (DSSC). As a luminescence medium, Gd2O3:Eu3+ improved light harvesting via conversion luminescence and increased the photocurrent of the DSSC. As a p-type dopant insulating rare earth oxides form an energy barrier, and the Gd2O3:Eu3+ elevated the energy level of the oxide film and increased the photovoltage. The photoelectric conversion efficiency for a DSSC with Gd2O3:Eu3+ doping (6:100) reached 7.01%, which was 17.4% higher than the photoelectrical conversion efficiency of a DSSC without Gd2O3:Eu3+ doping.
