摘    要:用电子束辐照了纳米TiO2多孔薄膜,并将其应用于染料敏化太阳电池,结果表明,电子束辐照可以提高太阳电池的短路电流,而开路电压基本不变.运用XRD分析了电子束辐照前后纳米TiO2多孔薄膜的晶型和晶粒度,发现电子束辐照不会造成纳米TiO2由锐钛矿相向金红石相转变,其晶粒度随电子束辐照注量的增加,存在着先增大、再减小,然后再增大的趋势.运用XPS分析了电子束辐照前后纳米TiO2多孔薄膜中Ti、O的化学状态,说明电子束辐照主要是使纳米TiO2多孔薄膜中氧充足状态的O1s逐渐减少,而不是通过Ti3+来改善太阳电池的性能.

Abstract:The nanocrystalline TiO_2*2porous film irradiated by the electron beam was applied to dye-sensitized solar cells. The results showed that electron beam irradiation could improve the short circuit current, while the open circuit voltage remained constant. The phase and diameter of the nanocrystalline TiO_2 porous film before and after irradiation were characterized by XRD,and it was found out that electron beam irradiation did not bring about phase transform of TiO_2 from anatase to rutile,and that with the enhancement of electron beam irradiation flux, the diameter of TiO_2 increased first from 12.11 nm to 14.00 nm,then decreased until it dropped to 12.13 nm,and then augmented with further irradiation. The chemical composition of Ti and O in the nanocrystalline TiO_2 film was analyzed by X-ray photoelectron spectroscopy(XPS). Experiment results showed that the oxygen sufficient region (O_(1s)) decreased with the increase of electron beam irradiation flux,and that it was the decrease of the oxygen sufficient region (O_(1s)) not the Ti~(3+) that improved the performance of dye-sensitized solar cells.
Keywords:TiO_2  electron beam  solar cell
