摘要

采用溶胶-凝胶法制备了TiO

/Eu

下转换薄膜，并对其光学特性和光电性能进行了分析。将其应用到染料敏化太阳能电池（DSSC）中，利用其下转换特性将部分紫外光转换为能被染料吸收利用的可见光，提高了DSSC的光照强度，促进了短路电流的增大。荧光光谱显示，下转换薄膜在受到394 nm紫外光照射时可发射出550~640 nm的可见光，具有下转换功能特性。下转换薄膜可以增加电池对太阳光的吸收范围，当涂有二层下转换薄膜时，短路电流密度从8.05 mAcm

-2

提高到9.62 mAcm

-2

，光电转换效率从3.67%提高到4.32%，转换效率相对提高了17.7%。

Abstract

TiO

/Eu

down-conversion film was prepared by sol-gel method

and its optical and photoelectric properties were analyzed. Applying it to dye-sensitized solar cells (DSSC)

partial UV light can be converted to visible light and absorbed by dye according to its down-conversion feature

as thus

the visible light intensity and short circuit currents are improved. The fluorescence spectra show that the down-conversion film can emit 550-640 nm visible light under 394 nm UV light excitation

which indicates a down-conversion feature of the film. The down-conversion film can increase the wavelength range of DSSC absorption. When bilayer down-conversion films are coated on DSSC

the short circuit current increases from 8.05 mAcm

-2

to 9.62 mAcm

-2

the photoelectric conversion efficiency increases from 3.67% to 4.32%.
