Abstract:	摘要： The present study focuses on enhancing the efficiency of bifacial and back-illuminated dye-sensitized solar cells (DSCs) by incorporating SiO2 mesoporous layer on TiO2 electrode. The performance of DSCs is investigated by UV–visible spectroscopy, incident photon conversion efficiency (IPCE) and electrochemical impedance spectroscopy (EIS). It is observed that the current ratio of back- to front-DSC increases with the increase in the thickness of SiO2 layer, which in turn influences the incident light to dyed-TiO2 electrode, especially in the wavelength of 400–600 nm. The Ti foil based flexible small (0.28 cm2) and sub-module (5 cm × 10 cm) DSCs having this modification show high conversion efficiencies of 6.76 and 5.54% respectively under 100 mW cm−2 (AM 1.5). [Display omitted] ► Coating SiO2 mesoporous layer on TiO2 electrode improves the incident light into dye-sensitized solar cells. ► Coating SiO2 layer on TiO2 porous electrode shows an increase of JSC by approximately 17.6%. ► Ti foil based flexible sub-module DSC (5 cm × 10 cm) shows high conversion efficiencies of 5.54% under 1 sun irradiation. 出版者： Elsevier B.V 出版日期： 2013-06-15 出處： Journal of power sources, 2013-06, Vol.232, p.1-6 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2013 Elsevier B.V. 識別號： ISSN: 0378-7753 識別號： EISSN: 1873-2755 識別號： DOI: 10.1016/j.jpowsour.2012.12.094
