Core-shell structured TiO/LiCO electrode was successfully synthesized by eco-friendly solution growth technique. TiO/LiCO electrodes were characterized using X-ray Diffractometer (XRD), Scanning electron microscopy (SEM) and photocurrent-voltage measurements. The synthesized core-shell electrode material was sensitized with tetrabutylammonium cis-di(thiocyanato)-N,N'-bis(4-carboxylato-4'-carboxylic acid-2,2'-bipyridine)ruthenate(II) (N-719). The performance of dye-sensitized solar cells (DSCs) based on N719 dye modified TiO/LiCO electrodes was investigated. The effect of various shell thickness on the photovoltaic performance of the core-shell structured electrode is also investigated. We found that LiCO shells of all thicknesses perform as inert barriers which improve open-circuit voltage (V) of the DSCs. The energy conversion efficiency was greatly dependent on the thickness of LiCO on TiO film, and the highest efficiency of 3.7% was achieved at the optimum LiCO shell layer.
核壳结构的 TiO/LiCO 电极通过环保的溶液生长技术成功合成。采用 X 射线衍射仪（XRD）、扫描电子显微镜（SEM）和光电电流-电压测量对 TiO/LiCO 电极进行了表征。合成的核壳电极材料用四丁基铵顺式-二（硫氰酸根）-N,N'-双（4-羧基-4'-羧酸-2,2'-联吡啶）钌（II）（N-719）敏化。基于 N719 染料修饰的 TiO/LiCO 电极的染料敏化太阳能电池（DSC）的性能进行了研究。还研究了不同壳层厚度对核壳结构电极光伏性能的影响。我们发现，所有厚度的 LiCO 壳层都表现为惰性屏障，提高了 DSCs 的开路电压（V）。能量转换效率很大程度上取决于 TiO 薄膜上 LiCO 的厚度，在最佳的 LiCO 壳层下，获得了 3.7%的最高效率。
