In this research, TiO₂-RGO composites were produced using the hydrothermal method. These composite structures were used in the phonoanodes of liquid junction solar cells. This study examines recombination mechanisms in liquid junction quantum dot sensitized solar cells (QDSSCs) with reduced graphene oxide (RGO) doped TiO₂ nanocomposite photoanodes, using the transient photo-current analysis method. RGO doped composite photoanode liquid junction solar cells exhibit electron lifetimes up to four times longer than pure TiO₂ photoanode. This increase indicates that new electron transport paths emerged within the composite thanks to RGO, that a significant reduction was achieved in the back-transfer of electrons and that recombination mechanisms were suppressed.

在这项研究中，使用水热法制备了TiO ₂ -RGO复合材料。这些复合结构用于液接太阳能电池的声阳极。本研究使用瞬态光电流分析方法研究了还原型氧化石墨烯（RGO）掺杂的TiO ₂纳米复合光阳极在液接量子点敏化太阳能电池（QDSSCs）中的复合机理。RGO掺杂的复合光阳极液结太阳能电池的电子寿命是纯TiO _2光阳极的四倍。这种增加表明，由于使用了RGO，复合材料中出现了新的电子传输路径，电子的反向转移显着减少，并且复合机理得到了抑制。
