Study On The Preparation Of All-solid-state F-DSSC On Manganese Plated Electrode

As a low-cost, renewable green energy, solar energy is extremely expected to become a global energy. The dye-sensitized solar cell(DSSC) has advantages of lowcost, abundant raw materials, so it becomes hotspot in research of solar cells. The researchers initially used rigid flat as the DSSC anode base, The traditional rigid flat photovoltaic cells have some problems, such as fragile conducting glass, high hardness, So it hinders the product development of industrialization. In recent years, a new kind of fibrous DSSC attracts researchers’ attention. The researchers introduce the high rate of bending fiber electrode to all-solid-state DSSC, it brings a series of new problems to study of the photovoltaic device structure and optimize the performance of the F-DSSC, and it also expands the choice of electrode substrate to a broader range.As Ti and Fe have disadvantages, such as high melting point, high mass density, and the hardness to composite with other fibers, Mn has advantages, such as cheap price, light weight, good corrosion resistance, good conductivity and low surface working function. In our work, we use Mn as substrate materials of All-solid-state DSSC, this can further reduce the cost of the DSSC and broaden the application scope of electrode substrate materials. A series of TCO-less, low-cost composite conductive fiber materials can be deposited onto conductive metal fiber materials and non-conductive polymer fiber materials through the electroplating and chemical plating technology, which firstly are applied to All-solid-state F-DSSC. The use of the new electrode can avoid the problem of Ti and Fe machine-shaping requires high temperature and the hardness to composite with other fibers. The research mainly includes the following:Study through electroplating technology, composite conductive fiber manganese material was prepared on metal conductive fiber copper, which firstly is applied to Allsolid-state F-DSSC. The study found that Mn layer morphology and Zn O nanometer array structure have a big impact on the photoelectric performance of All-solid-state FDSSC, When the voltage was 3.1 V, the time was 3min and the Zn2+ concentration was 0.04 M, the performance of the obtained Zn O-base All-solid-state F-DSSC was better than that of All-solid-state F-DSSC based on traditional Ti wire and stainless steel wire substrate; Furthermore, after coating a layer of Mn on different metal wire substrates, their performance of DSSC could all be improved; Influence of the pressure between the photoanode and the counter electrode on the performance of All-solid-state F-DSSC show that the optimal voltage is 0.1MPa; All-Solid-state DSSC stability test show that the performance of All-solid-state DSSC has no obvious attenuation after storaging 3000 h in the air. A similar technology could develop a new basal material that has application prospect in the field of All-solid-state DSSC fiber;Research through the combination of electroplating and chemical plating technology, polymer fiber PBT/Cu/Mn was prepared on non-conductive polymer PBT, which firstly is applied to All-solid-state F-DSSC. The study found that Mn layer morphology have a big impact on the photoelectric performance of All-solid-state FDSSC based on PBT/Cu/Mn wire, When the voltage was 3.8 V, the time was 1min and the Cu2+ concentration was 0.034 M, The performance of All-solid-state F-DSSC based on PBT/Cu/Mn wire was even the same as that of All-solid-state F-DSSC based on traditional Ti wire substrate.
