摘    要:采用水热法制备了TiO2和CdSe两种纳米棒材料,将两种纳米材料制备成TiO2/CdSe复合纳米棒膜电极,并在复合膜上电化学聚合生成聚3-甲基噻吩poly(3-methylthiophene)(PMeT),研究了其光电化学性能.实验表明,当TiO2与CdSe的物质的量复合比为2:1,PMeT的聚合时间为40s,在电极电势为-0.2V下ITO/TiO2/CdSe/PMeT电极光电转换效率(IPCE)达到56%,对比ITO/TiO2/CdSe复合膜电极在长波方向的光电转换效率明显提高,光吸收截止波长发生了明显的红移.同时以ITO/TiO2/CdSe/PMeT组装了简易的杂化太阳电池,初步研究了光电池性能,光电池总效率为0.08%,Voc=0.4V,jsc=0.61mA/cm2,ff=0.33.

关 键 词:TiO2纳米棒  CdSe纳米棒  聚3-甲基噻吩  杂化太阳电池

Abstract:TiO2 and CdSe nanorods were prepared by a hydrothermal method.The photoelectrochemical properties of TiO2/CdSe composite film and TiO2/CdSe/PMeT film were investigated.The experiment results showed that the incident photon to current conversion efficiency (IPCE) of TiO2/CdSe/PMeT was obviously increased in comparison to that of TiO2/CdSe composite film.The experiment results showed that the p-n heterojunction existed in the TiO2/CdSe/PMeT nanostructure film,which favored the separation of electron-hole pair...
Keywords:TiO_2 nanorod  CdSe nanorod  poly(3-methylthiophene)  hybrid solar cell
