| 中文摘要 | the performance and electron recombination kinetics of dye-sensitized solar cells based on tio(2) films consisting of one-dimensional nanorod arrays (nr-dsscs) which are sensitized with dyes n719, c218 and d205, respectively, have been studied. it has been found that the best efficiency is obtained with the dye c218 based nr-dsscs, benefiting from a 40% higher short-circuit photocurrent density. however, the open circuit photovoltage of the n719 based cell is 40 mv higher than that of the organic dye c218 and d205 based devices. investigation of the electron recombination kinetics of the nr-dsscs has revealed that the effective electron lifetime, tau(n), of the different dye based nr-dsscs shows the sequence of c218 > d205 > n719. the higher v(oc) with the n719 based nr-dssc is originated from the more negative energy level of the conduction band of the tio(2) film. in addition, in comparison to the dsscs with the conventional nanocrystalline particles based tio(2) films, the nr-dsscs have shown over two orders of magnitude higher tau(n) when employing n719 as the sensitizer. nevertheless, the tau(n) of the dsscs with the c218 based nanorod arrays is only ten-fold higher than that of the nanoparticles based devices. the remarkable characteristic of the dye c218 in suppressing the electron recombination of dsscs is discussed. |
