分等级锐钛矿TiO_2纳米线阵列的制备及其在CdSe量子点敏化太阳电池中的应用
2014年
量子点敏化太阳电池是一种新型的第三代高效太阳电池,具有极大的应用前景。本文利用水热法,首先在柔性的钛片基底上生长了光滑的TiO2纳米线阵列,并通过第二步水热反应制备出具有分支结构的分等级TiO2纳米线阵列,研究了其在CdSe量子点敏化太阳电池中的应用。实验结果表明,具有分支结构的分等级材料具有更高的表面积以负载敏化剂,同时保持了一维纳米阵列高效的电子传输特性,因此相比于光滑纳米线阵列,其光电转换效率提升近一倍,在标准光强下测试达到0.72%。

D-A-π-A organic sensitizers containing a benzothiazole moiety as an additional acceptor for use in solar cells被引量:2
2013年
Three novel triphenylamine-based D-A-r-A-featured dyes (Zl-Z3) have been designed, synthesized and characterized for use in dye-sensitized solar cells. Benzothiazole was incorporated as an additional acceptor, which greatly enhanced the molar ex- tinction coefficient of the dyes. Various conjugated linkers, such as benzene, furan and thiophene, were also introduced to con- figure the novel D-A-n-A framework in order to prolong electron flow and active transportation. Among all dyes, Z2 contain- ing a thiophene linker exhibited the maximum overall conversion efficiency (r/) of 4.16% (Jsc = 9.27 mA cm-2, Voc = 642 mV, FF = 0.70) under standard global AM 1.5 G solar condition.
