本工作制作了基于介孔 TiO2/石墨烯修饰的 TiO2纳米线光阳极的染料敏化太阳能电池，并进行表征。光阳极结合了介孔TiO2的高染料吸附率，TiO2纳米线的高载流子传导率和石墨烯的高电子收获能力等优点，使器件光电转换效率有了很大的提高。制作出的染料敏化太阳能电池光电转换效率高达7.58%，比纯纳米线制作的电池约提高了1.5倍，在拥有相似一维结构的染料敏化太阳能电池中具有较大优势。
Novel hybrid dye-sensitized solar cells (DSSCs) were fabricated and characterized, employing a com-posite photoanode of TiO2 nanowires infiltrated with graphene-decorated mesoporous TiO2. Combining the mer-its of the high dye loading of mesoporous TiO2, high light harvesting capability with the carrier transport of TiO2 nanowires and the high electron collection efficiency from graphene, the overall performance of such photoanode was significantly improved. The obtained DSSCs showed a power conversion efficiency of up to 7.58%, about 1.5 times higher than the pristine TiO2 nanowires, which was quite competitive compared with the similar 1D structured photoanode of DSSCs.
