| 英文摘要 | ultrapure tio2 nanoparticles (similar to 5 nm in size) were supported on "inert" batio3 films by ticl4 treatment, which was used to fabricate dye-sensitized solar cells (dsscs). the optimized electrode, designated as batio3/tio2(4), was obtained upon four cycles of ticl4 treatment. dssc with batio3/tio2(4) electrode exhibits superior power conversion efficiency (pce) compared to that with conventional anatase tio2 (similar to 25 nm in size) electrode. the interfacial charge recombination kinetics was investigated by electrochemical impedance spectroscopy (eis) and intensity-modulated photocurrent/photovoltage spectroscopy (imps/imvs). in contrast to dssc with anatase tio2 electrode, the dramatically enhanced electron lifetime for dssc with batio3/tio2(4) electrode could be attributed to the decrease of recombination reaction at the tio2 photoelectrode/electrolyte interface. it is proposed that the lower interfacial charge recombination can be related to the relatively shallower trap distributions in dssc with batio3/tio2(4) electrode.
