![]() ![]() Here the incorporation of semiconducting nanoparticles at the tips of aligned TiO 2 nanotubes after TiCl 4 treatment helped to make the outer surface uniform. The resulting Ti wire was finally wound with an aligned MWCNT fiber to produce the wire-shaped polymer solar cell.Īccording to the researchers, the nanocrystalline semiconductor oxide layer played a crucial role in providing pathways for charge transport. Two polymer layers were then dip-coated onto the modified Ti wire. In a typical fabrication, a Ti wire was modified by growing aligned titania nanotubes on the surface by electrochemical anodization, followed by coating of a layer of titania nanoparticles. The above image schematically shows the structure of the wire-shaped polymer solar cell (PSC) with a titanium (Ti) wire and an aligned multiwalled carbon nanotube (MWCNT) fiber as cathode and anode, respectively. Schematic illustration of the wire-shaped polymer solar cell. Huisheng Peng's research group in the Department of Macromolecular Science at Fudan University, and first author of the paper, tells Nanowerk. "We found that the titania nanoparticle enhance the adsorption of photoactive materials and charge transport, which increased the energy conversion efficiency by 36% compared with the wire-shaped polymer solar cell without the titania nanoparticle under the same condition," Zhitao Zhang, a student in Prof. These miniature polymer solar cell wires, when woven into textiles, can serve as a power source. ![]() The aligned carbon nanotube fiber enabled high flexibility and stability of the resulting polymer solar cell. Reporting their results in the Maonline edition of Advanced Energy Materials ( "Weaving Efficient Polymer Solar Cell Wires into Flexible Power Textiles"), researchers in China have developed a novel efficient wire-shaped polymer solar cell by incorporating a thin layer of titania nanoparticles between the photoactive material and electrode. ![]() Today, we look at recent developments that would actually allow your T-shirt to generate power from its interwoven solar cell wires. In a previous Nanowerk Spotlight we reported on wearable energy storage ( "Nanotechnology T-shirt to replace batteries? Towards wearable energy storage"). Such e-textiles will have the revolutionary ability to sense, act, store, emit, and move – think biomedical monitoring functions or new man-machine interfaces – while ideally leveraging an existing low-cost textile manufacturing infrastructure.Īll these wearable and potentially textile-embedded electronic gadgets will require power and it wouldn't make sense to have to plug your sleek flexible sleeve display into a bulky lithium-ion battery brick. ( Nanowerk Spotlight) Forget about Google Glass or the latest smart watch announcements – the future will belong to electronic textiles (e-textiles) that will allow the design and production of a new generation of garments with built-in unobtrusive sensors and a variety of electronic functions.
