Chinese Science Bulletin, 2013Co-Authors: Gentian Yue, Miaoliang Huang, Jianming Lin, Leqing Fan, Yaoming Xiao, Ying YaoAbstract:A Counter Electrode for dye-sensitized solar cell (DSSC) was prepared by coating poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) with high transparency and adhesion on a conducting FTO glass at low temperature. The surface morphology, conductivity, sheet resistance, redox properties and photoelectric properties of the PEDOT:PSS/carbon Electrodes were observed using scanning electron microscopy, a four-probe tester and a CHI660D electrochemical measurement system. The experimental results showed that DSSCs had the best photoelectric properties for PEDOT:PSS/carbon Counter Electrodes annealed at 80°C under vacuum conditions. The overall energy conversion efficiency of the DSSC with PEDOT:PSS/carbon Counter Electrode and barrier layer reached 7.61% under irradiation from a simulated solar light with intensity of 100 mW/cm2 (AM 1.5). The excellent photoelectric properties, simple preparation procedure and low cost allow the PEDOT:PSS/carbon Electrode to be a credible alternative Electrode for use in DSSCs.

high performance platinum free Counter Electrode of molybdenum sulfide carbon used in dye sensitized solar cells
Journal of Materials Chemistry, 2013Co-Authors: Miaoliang Huang, Jianming Lin, Gentian Yue, Yaoming Xiao, Jengyu LinAbstract:A high porous molybdenum sulfide–carbon (MoS2–C) hybrid film was prepared by using an in situ hydrothermal route. The MoS2–C hybrid film served as a low-cost and high efficient platinum-free Counter Electrode for a dye-sensitized solar cell (DSSC). The cyclic voltammetry, electrochemical impedance spectroscopy and Tafel curve analysis indicate that the MoS2–C Electrode possesses low charge transfer resistance on the electrolyte–Electrode interface, high electrocatalytic activity and fast reaction kinetics for the reduction of triiodide to iodide at the Counter Electrode, which is due to large specific surface area and special structure and compositions of MoS2–C film. A DSSC with the novel MoS2–C Counter Electrode achieve a high power conversion efficiency of 7.69% under standard light illumination, which exceeds that of the DSSC with a Pt Counter Electrode (6.74%).

Activated graphene nanoplatelets as a Counter Electrode for dye-sensitized solar cells
Journal of Applied Physics, 2016Co-Authors: Jiawei Gong, Zhengping Zhou, K. Sumathy, Huojun Yang, Qiquan QiaoAbstract:Activated graphene nanoplatelets (aGNPs) prepared by a hydrothermal method using KOH as activating agent were used as Counter Electrode for high efficiency dye-sensitized solar cells (DSSCs). After the KOH activation, the scanning electron microscopy image shows that aGNPs demonstrate a more curled, rough, and porous morphology which could contain both micro- and mesopores. The KOH activation changed the stacked layers of GNPs to a more crumpled and curved morphology. The microstructure of large pores significantly increased the Electrode surface area and roughness, leading to the high electrocatalytic activity for triiodide reduction at the Counter Electrode. The DSSCs fabricated using aGNP as Counter Electrodes were tested under standard AM 1.5 illumination with an intensity of 91.5 mW/cm2. The device achieved an overall power conversion efficiency of 7.7%, which is comparable to the conventional platinum Counter Electrode (8%).

electrospun carbon nanofibers with surface attached platinum nanoparticles as cost effective and efficient Counter Electrode for dye sensitized solar cells
Nano Energy, 2015Co-Authors: Alex Aboagye, Qiquan Qiao, Hytham Elbohy, Ajit D Kelkar, Xuefeng Qian, Lifeng ZhangAbstract:Abstract Dye-sensitized solar cells (DSCs) have attracted incredible attention in recent years as relatively inexpensive alternative to silicon solar cells. Conventionally, a transparent fluoride-doped tin oxide (FTO) conductive glass with a thin layer coating of platinum (Pt) is used as Counter Electrode in DSCs. The widespread use of Pt as Counter Electrode in DSCs is due to its catalytic capability for I 3 - reduction in electrolyte. However, Pt is costly and can be affected by the corrosive nature of I - /I 3 - redox couple, which makes it a less desirable candidate for use in industrial scale manufacturing. In this study, carbon nanofibers with surface-attached Pt nanoparticles were prepared by stabilization and carbonization of electrospun polyacrylonitrile (PAN) nanofibers and subsequent controllable Pt nanoparticle growth on the obtained carbon nanofiber surface through redox reaction. The hierarchical carbon nanofibers with surface-attached Pt nanoparticles (ECNFs-PtNPs) were then employed as cost-effective Counter Electrode in DSCs. The effects of size, morphology, and loading of Pt nanoparticles on performance of DSCs were investigated. Compared to conventional Counter Electrode, the Counter Electrode that was made of ECNFs-PtNPs exhibited larger open circuit voltage (V oc ). The DSCs that were made with ECNFs-PtNPs Counter Electrode demonstrated excellent solar energy conversion efficiencies in the range of 7% to 8%.

Thin Solid Films, 2014Co-Authors: Anastasiia Iefanova, Qiquan Qiao, Umesh Gautam, Prashant Poudel, Daren Davoux, Jeevan Nepal, Venkataiah Mallam, Brian A. Logue, Farrokh BaroughiAbstract:Abstract A method for fabrication of highly transparent platinum Counter Electrodes (CEs) has been developed based on spray coating of Pt nanoparticles (NPs) on hot substrates. This method leads to 86% reduction in Pt consumption reducing the Pt cost per peak watt of Counter Electrode from $0.79/Wp down to $0.11/Wp compared to the conventional Pt Counter Electrodes made by sputter deposition. The simplicity and low cost of this method provide a basis for an up-scalable fabrication process. The Pt NP layer is over 88% transparent, leading to overall transparency of 80% when incorporated with indium tin oxide/glass substrates for functional Counter Electrodes. This Counter Electrode exhibits a large surface area and high catalytic activity, comparable to that of the conventional opaque CEs. Semi-transparent dye-sensitized solar cells fabricated based on this Counter Electrode showed 6.17% power conversion efficiency.

Nano Energy, 2014Co-Authors: Prashant Poudel, Amit Thapa, Hytham Elbohy, Qiquan QiaoAbstract:Abstract Carbon nanoparticles (CNPs) were used to support platinum nanoparticles as Counter Electrodes in dye-sensitized solar cells (DSCs). Carbon nanoparticles provided larger effective surface area and better exposure of Pt nanoparticles resulting in very efficient electrocatalytic performance as Counter Electrode. DSCs fabricated using such Counter Electrode showed enhanced efficiency owing to lower series resistance and higher fill factor as a result of reduced charge transfer resistance. The overall power conversion efficiency of the DSC devices using these CNP/Pt Counter Electrodes reached 8.12% as compared to 7.49% for reference platinum Counter Electrode DSCs under 1 sun illumination.
