But so far, the efficiency of actual devices made of such nanoparticles has been considerably lower than that of conventional silicon solar cells. That’s largely because it has proved difficult to harness the electrons that are generated to create a current. Indeed, without the carbon nanotubes, electrons generated when light is absorbed by titanium-oxide particles have to jump from particle to particle to reach an electrode. Many never make it out to generate an electrical current. The carbon nanotubes “collect” the electrons and provide a more direct route to the electrode, improving the efficiency of the solar cells. The new carbon-nanotube and nanoparticle system is not yet a practical solar cell. That’s because titanium oxide only absorbs ultraviolet light; most of the visible spectrum of light is reflected rather than absorbed.

a one-molecule-thick layer of light-absorbing dye is applied to the titanium-dioxide nanoparticles to absorb the visible spectrum.Cotton T-shirts absorbing energies:Flexible energy storage device that could charge your cell phone or your iPodsFigure 2 T-shirt absorbing energyMechanism:A cotton shirt is taken. Soaked it in a solution of fluoride, dried it and baked it at high temperature. They excluded oxygen in the oven to prevent the material from charring or simply combusting.The surfaces of the resulting fibers in the fabric were shown by infrared spectroscopy to have been converted from cellulose to activated carbon. Yet the material retained flexibility; it could be folded without breaking.

The once-cotton T-shirt proved to be a repository for electricity. By using small swatches of the fabric as an electrode. Then this activated carbon textile, acts as a capacitor.

Capacitors are components of nearly every electronic device on the market, and they have the ability to store electrical charge.Hybrid fabric, in which the activated carbon textile fibers are coated with nanostructured manganese oxide, improved the energy storage capability beyond the activated carbon textile alone. The hybrid super-capacitors were resilient: even after thousands of charge-discharge cycles, performance didn’t diminish more than 5 percent.This is an appealing method and is a very inexpensive, green process.Fibers to store energy:Batteries store energy. Standard battery contains a metallic foil that is covered with a substance called an electrolyte and then coiled inside the battery.

Researchers have now produced batteries using fabric.Figure 3 Fibers to store energyMechanism:The fabric is soaked in ink containing nanoparticles. One piece of fabric is soaked in nanoparticles that make it act like an anode, and another piece to which it’s attached is soaked in different nanoparticles to make it act like a cathode. (The exchange of ions between an anode and a cathode causes a battery to release or store electrons.

)This fabric, which the researchers have named E-Textiles, is much less costly to produce than the metallic foil used in traditional batteries.If you vary the ingredients in the ink into which the fabric gets dipped, you can create a super-capacitor, which is another device used to store energy. The ink used to make the batteries contains oxide nanoparticles, and the ink used to make the super-capacitors contains single-walled carbon nanotubes.

Because textiles soak up the conductive ink so well, they make very efficient storage devices. They can hold about three times as much energy as your mobile phone battery and are stronger and more durable.Fibers as a source of heat:Although the sun is a virtually inexhaustible source of energy, it’s only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat.

Manufacturing the new material requires just a two-step process To make the film (That can be incorporated into many different materials including glass or even fabric) capable of storing a useful amount of heat, materials used was called azobenzenes that change their molecular configuration in response to light. The azobenzenes can be stimulated by a tiny pulse of heat, to revert to their original configuration and release much more heat in the process, And its responsiveness to the activating heat pulse.Figure 4 Fiber as a source of heatConclusion:Although these technologies are not much common in the present world. But the researches are going on. The future of power textile is bright and flourishing. These products will bring revolutionary change in the world of technology by making energy easy to approach and feasible and less expensive. Every person will be generating power for his use by himself.Extract Materials From:http://news.mit.edu/2016/store-solar-heat-0107https://www.sciencedaily.com/releases/2012/06/120629211540.htmhttp://www.latimes.com/science/sciencenow/la-sci-sn-fabric-captures-energy-20161026-snap-story.htmlhttp://www.dummies.com/education/science/nanotechnology/fabric-that-produces-or-stores-electricity/https://www.technologyreview.com/s/407432/cheap-nano-solar-cells/
