纳米晶太阳能电池是通过将顺式二硫氰酸双(2,2'-联吡啶-4,4'-二羧酸)钌(II)掺入溅射沉积的氧化钛薄膜中制成的。经过吡啶处理后，在 100 W/m(2) 的太阳光强度下，光电转换效率高达 7%，几乎与采用胶体制备的二氧化钛的传统纳米晶电池相同。透射电子显微镜显示出平行的笔状微观结构，二次离子质谱显示染料的掺入是均匀的，除了溅射膜的底部部分，其中孔隙率的降低似乎限制了染料的渗透。 (C) 2000 Elsevier Science B.V. 保留所有权利。
Nanocrystalline solar cells were made by incorporation of cis-dithiocyanato-bis(2,2'-bipyridyl-4,4'-dicarboxylate) ruthenium (II) into sputter deposited titanium oxide films. After a pyridine treatment, it was possible to achieve a photoelectric conversion efficiency as high as 7% for a solar intensity of 100 W/m(2) - almost the same as for conventional nanocrystalline cells with colloidally prepared titanium oxide. Transmission electron microscopy indicated a parallel penniform microstructure, and secondary ion mass spectroscopy showed that the dye incorporation was uniform except in the bottom parts of the sputtered films where a decreased porosity seems to limit the penetration of the dye.
