摘要:研究了三种不同长度碳链取代的半菁类染料2-[4-(N,N-二羧乙基)氨基]苯乙烯基-1,3,3-三甲基苯并吲哚鎓碘(BIDC1)、2-[4-(N,N-二羧乙基)氨基]苯乙烯基-1-丁基-3,3-二甲基苯并吲哚鎓碘(BIDC2)和2-[4-(N,N-二羧乙基)氨基]苯乙烯基-1-辛基-3,3-二甲基苯并吲哚鎓碘(BIDC3)敏化太阳能电池的光电化学性能。其中BIDC1的敏化效果最好,在100mW/cm2氙灯光源下,开路电压、短路电流、填充因子和转换效率分别是430mV、1.31mA/cm2、0.52、0.29%。研究表明,随着半菁染料碳链取代基的增长,光电转换效率逐渐降低。
The photoeleetroehemieal properties of three new hemieyanine dyes with different carbon chain, 2-[ 4- ( N,N-diearboxyethyl ) amino ] phenylethenyl-1,3,3-trimethyl benz[e]indolium iodide ( BIDC1 ), 2-[ 4-( N,N- diearboxyethyl ) amino ] phenylethenyl-1-buty-3,3-dimethyl benz[e]indolium iodide ( B1DC2 ) and 2-[ 4-( N,N- diearboxyethyl)amino]phenylethenyl-3,3-dimethyl-1-octyl benz[e]indolium iodide(BIDC3), have been studied. It is found that BIDC1 is the best candidate with conversion yield of 0.29%, short-circuit photoeurrent of 1.31mA/cm^2, open-circuit voltage of 430mV and fill factor of 0.52 under illumination with 100roW/era2 white light from a xenon lamp. The longer carbon chain the hemieyanine holds, the less charge recombination will occur from TiO2 to oxidation state dye or eleetrolye. The conversion efficiency η also decreases along with the extension of carbon chain.
