Abstract: It is universally known that N719 dye can only absorb visible light, which has always been a limitation for its application in dye-sensitized solar cells (DSSCs). In this study, a rare-earth upconversion luminescent material was introduced to broaden the absorption spectrum of N719 sensitized TiO2 photoanodes, enhance light harvesting efficiency, and further improve the perfor-mance of DSSCs devices. Firstly, the upconversion luminescent material of Yb3+/Er3+ doped La(OH)3 had been successfully synthesized via the simple hydrothermal method by controlling the pH values of precursor solution. Then, different contents of these Yb3+/Er3+ doped La(OH)3 powders were further mixed with P25 for the preparations of TiO2 paste. Finally, the TiO2 photoanodes with different contents of the upconversion luminescent materials were made by doctor-blade method for further application in DSSCs. As a result, through the introduction of upconversion luminescent materials, the scope of spectral absorption was broadened, and when the doping amount was up to 3%, the highest power conversion efficiency of DSSCs reached 8.3% with the maximum short-circuit current density of 17.72 mA·cm-2 .
