| As a renewable, energy problem increasingly highly, the development of new energy is extremely expected, which would replace the fossil fuels. The dye-sensitized solar cells(DSSC) as the third generation of solar cells has many advantages such as abundant material sources, high light efficiency and low-cost.in order to achieve the large-scale application of dye sensitized battery.It is very important to select the basal materials. The traditional cells of rigid flat photovoltaic have many problems with poor resistance of external force and restriction of large space which restrict the diversity of product and hinder the product development of industrialization. But recently,researchers try to use conductive fibers as electrode substrate to assemble into a new fiber DSSC.The dye-sensitized solar cells with its unique flexible woven feature could overcome the above problems.The conductive fibers were selected as the base material, where to grow Zn O nanometer semiconductor assembly as working electrode through the winding or weaving method.The assemble flexible dye sensitized cells with its unique flexible woven have many advantages low-cost, abundant raw materials, simple process of preparation and largely used of space.For the first time, the interfaces in the fiber shaped DSSC were heavily bended which has leaded to the increase of interfacial stress, and brought a new challenge to the study of F-DSSC, and also expanded the electrode substrate by the conventional titanium or stainless steel to a broader range, in order to decrease the cost. This study firstly presented an equivalent circuit model for the liquid F-DSSC based on the ideal structure of unstrained. Then based on the established equivalent model, through a simple wet-process electroplating and electroless, which to deposite a metal layer in the material surface, and through a simple hydrothermal synthesis process to grow Zn O nanorod array on the based surface, the preparation of a low-cost flexible zinc composited fiber electrode. In this paper, the research content mainly includes the following:①Zinc is a type of metal with low work function(4.3 e V) and good conductivity.A thin and compact layer of Zn O will form automatically over the metal Zn upon exposing to the air, which may provide a promising self-repairing mechanism for defects on the metal\Zn O interface. It can expand the range of technology which can beapplied to other composite fiber conductive materials, to reduce the cost, and improve the energy-conversion efficiency.②Low-cost zinc-plated wire photoanode for the fabric-type flexible DSSCs were for the first time.And through a simple hydrothermal synthesis process to grow Zn O nanorod array on the based surface, then assembed DSSC. The study showed that:different zinc layer morphology and Zn O nanorod array structure markedly influenced the performance of electrode. When the voltage was 2.0 V and the Zn2+ concentration was 0.03 M, the performance of the obtained Zn O-base fiber photo-anode cell was more than that of traditional Ti wire and stainless steel wire substrate photo-anodes.It can expand the range of technology which can be applied to other composite fiber conductive materials.③This paper studies that, the influence of Ti O2 compact layer optical anode corrosion resistance. By comparing the battery I-V curve, at the same time electrochemical testing means were used. The study showed that: coated Ti O2 as the density of anode layer of light. Electrode anode corrosion resistance increasly, the performance of the obtained Zn O-base fiber photo-anode cell was changed a little. It is good that to extend the service life of the battery. |
