中文摘要：

染料敏化太阳能电池（DSSCs）作为硅太阳能电池的替代者引起了广大科研工作者的密切关注,然而由于DSSCs最大的太阳光吸收波长在可见光区域,限制了其光电转换效率。稀土上下转换材料通过将紫外或近红外光转换成电池可利用的可见光,应用到DSSCs中有效弥补DSSCs光吸收不足,同时还具有光散射作用、有效减小电子复合损失,提高电池稳定性。阐述了稀土对光上下转换机理,详述了近几年稀土上下转换材料在染料敏化太阳能电池中应用的研究进展。

英文摘要：

Dye-sensitized solar cells（DSSCs）have attracted extensive interest as an promising alternative to silicon solar cells.However,DSSCs have a maximum absorption in visible light of solar spectrum,which confines the power conversion efficiency.Rare earth up/down conversion materials were used to effectively make up for the shortage via converting ultraviolet and near-infrared radiation to visible emission in the DSSCs.At the same time,the light-scattering effect can reduce the recombination loss effectively and promote the stability of the DSSCs.The up/down conversion mechanism is pointed and recent research progress of applications based on rare earth up/down conversion materials in DSSCs is reviewed.
