Case Study

High-efficiency ZnO-based dye-sensitized solar cells with 1H,1H,2H,2H-perfluorodecyltriethoxysilane

Xie, Yahong, et al. Applied Surface Science 434 (2018): 1144-1152.

Charge recombination at the ZnO photoanode/electrolyte interface is one of the main limitations of the theoretical power conversion efficiency (PCE) of high-performance dye-sensitized solar cells (DSSCs). A hydrophobic film was decorated on the surface of dye-coated ZnO photoanode by 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES) hexane solution to reduce interfacial losses and thus promote charge transfer immersion. As a result, a high PCE of 8.22% was obtained, far exceeding the efficiency of 5.40% of conventional DSSCs without PFDTES treatment. This work comprehensively explains the electron injection, transfer, and recombination at the ZnO photoanode/electrolyte interface and provides a promising strategy for exploring efficient ZnO-based DSSCs.
The rinsed dye photoanode was first dried by air flow and then immersed in different concentrations (0, 1, 2, 3, 4 and 8 mM) at different time intervals (0, 6, 12, 18, 24 and 30 min). The PFDTES-treated dye photoanode was then rinsed with hexane several times to remove the PFDTES molecules physically adsorbed on the photoanode and then dried by air flow. The Pt counter electrode was placed below the PFDTES-treated N719 dye-sensitized photoanode. The electrolyte consisting of 0.5 M LiI, 0.05 M I and 0.1 M 4-tert-butylpyridine in 1:1 acetonitrile propylene carbonate was filled into the space between the two electrodes.

Preparation of superhydrophobic surface with 1H,1H,2H,2H-perfluorodecyltriethoxysilane

Shang, Qianqian, Yonghong Zhou, and Guomin Xiao. Journal of Coatings Technology and Research 11 (2014): 509-515.

The superhydrophobic surface based on silica particles was prepared by spraying the prepared silica suspension containing silica sol and silica microspheres on the substrate. The morphology of the silica particle coating can be controlled by changing the concentration of silica microspheres. The prepared silica particle coating is very rough and superhydrophilic, with a water contact angle of less than 5°. The surface silanol groups of the hydrophilic coating can be functionalized using 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTS) to form hydrophobic groups. The obtained surface exhibits excellent superhydrophobic properties with a water contact angle of up to 165.6±0.9° and a sliding angle of 3.5±0.4°. In addition, the superhydrophobic coating has good stability after being exposed to air for 3 months over a wide pH range.
The silica suspension was sprayed onto the glass substrate using compressed air (0.2 MPa) through a manual spray gun with a 0.3 mm diameter tip. Before spraying, the silica suspension was stirred for 15 min to prevent solidification, and only freshly prepared batches of silica suspension were used. After spraying, the samples were placed horizontally and dried overnight at room temperature. The glass substrates were cleaned for 3 h and ultrasonically treated in ethanol and acetone for 30 h. min and then rinsed thoroughly with deionized water before coating. The coating surface was hydrophobically modified by simple chemical vapor deposition (CVD) of PFDTS solution. The solution was prepared by mixing 0.5 g PFDTS and 1.0 g distilled water in 50 g methanol and stirring for 1 h. The coated glass substrate was placed in a sealed container containing 2.0 g PFDTS solution. The distance between the glass substrate and the PFDTS solution was 2.5 mm. The container was heated at 150°C for 3 hours to form a self-assembled PFDTS monolayer on the surface of the silica coating. After being removed from the container, the coated substrate was placed in an oven at 120°C for 1 hour to volatilize the unreacted PFDTS molecules on the coating.
