Design And Research Of Dye-sensitized Solar Cell Textile

The textile and apparel field is changing from traditional basic functions to more intelligently.Intelligent textiles require interdisciplinary and multidisciplinary knowledge research.Among them,the source of energy,which is the basis of intellectualization,is especially important in today’s increasingly scarce non-renewable resources.Clean energy is desperately needed.As a third generation solar cell,dye-sensitized solar cells（DSSCs）have become one of the alternatives to traditional hard single-crystal silicon solar cells because of their low cost,simple fabrication and adjustable color characteristics.This paper takes the design of dye-sensitized solar cell textiles as the research direction,from the preparation of photo-anode materials to the exploration of flexible textile-based DSSCs,to the combination of self-made functional garments.By using the textile technology-electrostatic spinning technology,fibrous titanium dioxide,zinc oxide/titanium dioxide composite fibers were prepared as DSSCs photoanode materials to explore the photovoltaic performance of batteries.It is found that the preparation of fibrous titanium dioxide by electrostatic spinning can increase the transfer rate of photogenerated electrons in the photo-anode,reduce the resistance,and have higher photoelectric conversion efficiency than that of the batteries made of commercial titanium dioxide.In addition,the specific surface area of Zn O/Ti O₂composite fibers prepared by electrospinning increases first and then decreases with the addition of Zn O,and is larger when Zn O:Ti O₂=2:1.The interface impedance between anode material and electrolyte decreases with the addition of Zn O,and increases with the addition of Zn O.When the doping ratio is Zn O:Ti O₂=1:2,the interface resistance of the photo-anode material/electrolyte is the smallest and the best result is obtained.The photoelectric conversion efficiency of the battery is 3.66%,which is the highest among all samples.Flexible textile-based DSSCs were explored with ITO/C by using copper-nickel-plated fabric as the photo-anode base and self-made high-efficiency photo-anode materials.The results show that DSSCs using copper-nickel coated fabrics have a low photoelectric conversion efficiency of only 0.73%.When the copper-nickel coated fabric is used as the base,the calcined resistance increases by 80.3%,the mechanical properties decrease by 96%,and there is much room for improvement as the DSSCs base.Finally,dye-sensitized solar textiles（solar functional clothing）need not only the innovative preparation of materials,but also the production of clothing materials,Style3D knowledge,ET clothing board and other knowledge.In this paper,the application of DSSCs in textile field is prospected from the design point of solar functional garment,the selection of garment fabrics,the determination of installation location of solar cells and functional components.
