中文摘要：

采用磁控溅射法,通过控制溅射时间在导电基底FTO上制备出了具有不同载Pt量的Pt/FTO对电极,分析了对电极的表面形貌、晶相结构、透过率等。同时,对不同光照模式下组装的染料敏化太阳能电池（dye sensitized solar cells,DSSCs）的光电性能进行了考察。实验表明,正照射模式下,溅射30 s制备的Pt/FTO对电极能获得优异的光电性能,其组装电池的最高能量转换效率达到8.3%,在正照射模式下具有很好的应用前景;由于所制备对电极透光性较差,背照射模式下组装电池的光电性能较低。

英文摘要：

The Pt/FTO counter electrodes with various platinum loading, adjusting by sputtering time, were prepared on conductive substrate FTO by magnetron sputtering. The morphology, crystallographic structure and light transmittance were analyzed. The photovohaie the Pt/FTO counter electrode were investigated performance of assembled dye sensitized solar cells （DSSCs） based on under front-side illumination mode and back-side illumination mode. It was found that the optimum power conversion efficiency of 8.3% was obtained in DSSCs assembled with 30s-sputering Pt/FTO counter electrode under front-side illumination mode, a good application prospects was exhibited. While the PCE of the DSSCs under back-side illumination mode was relatively low due to the poor light transmittance of the Pt/ FTO counter electrode.
