“…The Rct2 became small with increasing PS concentration from 0.0 g to 0.2 g, and Rct2 increased upon an increase in the PS concentration from 0.2 g to 0.8 g. The minimum Rct2 value of 4.55 Ω was obtained for the PS concentration of 0.2 g. A smaller Rct2 suggests longer electron lifetimes for power conversion efficiency 19) and decrease in total series resistance of the DSSCs. [2][3][4]17) The impedance spectra observations well coincide with the solar cell efficiency measurement results.…”

Light scattering enhancement is widely used to enhance the optical absorption efficiency of dye-sensitized solar cells. In this work, we systematically analyzed the effects of spherical voids distributed as light-scattering centers in photoanode films made of an assembly of zinc oxide nanoparticles. Spherical voids in electrode films were formed using a sacrificial template of polystyrene (PS) spheres. The diameter and volume concentration of these spheres was varied to optimize the efficiency of dye-sensitized solar cells. The effects of film thickness on this efficiency was also examined. Electrochemical impedance spectroscopy was performed to study electron transport in the electrodes. The highest power conversion efficiency of 4.07 % was observed with 12 µm film thickness. This relatively low optimum thickness of the electrode film is due to the enhanced light absorption caused by the light scattering centers of voids distributed in the film.

“…3,4) The most critical parameter for improved cell efficiency is the working electrode. Although TiO 2 nanocrystalline-based electrode structures are commonly used in DSSCs that yield energy conversion efficiency values as high as 11 %, 5) ZnO is also analyzed because of its better electron transport property than TiO 2.…”

“…Cyclonic APPs were used to perform surface treatments on electrospun poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) microfibrous membranes of DSSCs for improved efficiency [15]. APPs with a designated process were used for the reduction of Pt counter electrodes [16] and for the post surface treatments on TiO2 photoanodes [17][18][19] of DSSCs. A prolonged DBD treatment on TiO2 was shown to improve DSSCs with low-temperature-sintered TiO2 photoanodes [20].…”

Atmospheric pressure plasma jet (APPJ) technology is a versatile technology that has been applied in many energy harvesting and storage devices. This feature article provides an overview of the advances in APPJ technology and its application to solar cells and batteries. The ultrafast APPJ sintering of nanoporous oxides and 3D reduced graphene oxide nanosheets with accompanying optical emission spectroscopy analyses are described in detail. The applications of these nanoporous materials to photoanodes and counter electrodes of dye-sensitized solar cells are described. An ultrashort treatment (1 min) on graphite felt electrodes of flow batteries also significantly improves the energy efficiency. OPEN ACCESSCoatings 2015, 5 27
