Abstract:	摘要： Solid-state dye-sensitized solar cells (ss-DSCs) are fabricated using Z907 or its thiophene derivative, CYC-B11, as a dye, and poly(3-hexylthiophene) (P3HT) or (2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamine)9,9′)-spirobifluorene (OMeTAD) as a hole transport material (HTM). The effect of the structural compatibility of dye molecules with HTM on device performance is investigated. The CYC-B11/P3HT device has a much higher short-circuit current density than Z907/P3HT and CYC-B11/OMeTAD devices. Results from the incident photo-to-electron conversion efficiency and impedance measurements support the use of P3HT, in place of OMeTAD, as HTM markedly increases the photocurrent throughout the absorption spectrum of CYC-B11 and significantly reduces the charge-transfer resistance at the TiO2/dye/HTM interface. As a result, the CYC-B11/P3HT ss-DSC that is fabricated from a thin (0.5 μm) mesoporous TiO2 layer exhibits an outstanding power conversion efficiency of 3.66%. [Display omitted] ► High structural compatibility of dye and HTM enhances the regeneration of dye. ► P3HT can act as a hole conductor and co-sensitizer in an ss-DSC. ► Ultrathin CYC-B11/P3HT ss-DSC exhibits a power conversion efficiency of 3.66%. 出版者： Amsterdam: Elsevier B.V 出版日期： 2012-09-15 出處： Journal of power sources, 2012-09, Vol.214, p.113-118 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2012 Elsevier B.V. 版權： 2015 INIST-CNRS 識別號： ISSN: 0378-7753 識別號： EISSN: 1873-2755 識別號： DOI: 10.1016/j.jpowsour.2012.04.093 識別號： CODEN: JPSODZ
