The future want to charge your smart phone, in addition to wireless charging through the environment such as wireless networks, to encourage you to exercise more sports shoes, you can also use ink-jet plastic solar cells, as long as the light can absorb energy, And the application more diverse, such as your T-shirt, backpack, home curtains, etc. can be printed on the battery.An expert from Karlsruhe Institute of Technology in Germany also said that the use of inkjet printing production of solar panels can be said to be the most Cheap technology.
Dracula Technologies, a French startup solar company, is developing an appliqué solar cell made from a unique electrically conductive plastic that captures energy from either outdoor or indoor artificial light, the company that held last month in Paris, France, '2017 Hello One of Tomorrow's Summit's award-winning companies.
Traditional solar panels to use more silicon materials to capture solar energy, according to the current research and development in the laboratory of silicon-based solar cells (non-silicon air batteries), single crystal silicon cell efficiency of 25.0%, polycrystalline silicon cell efficiency of 20.4% CIGS thin-film cell efficiency of 19.8%, CdTe thin-film battery efficiency of 19.6%, amorphous silicon thin-film battery efficiency was 10.1%.
And the Dracula Technologies team is developing a conductive plastic that captures a wider range of wavelengths, called Light as Your Energy, and is made up of five layers of surface printing: the photoactive layer at the center, Side covered by the semiconductor chip to help printed in the outermost conductive color ink extraction charge.Scientist Sadok Ben Dkhil said that the direct absorption of direct light silicon material can not win this conductive material can capture the range of energy and thin film batteries have Light weight, non-toxic, collapsible, low cost and other advantages.
Right now, they can print square-shaped battery modules about 5 cm in length and width in less than an hour, in any color and shape (including transparency), said material physicist Sadok Ben Dkhil in an interview with "newscientist" , Which means that you can print this thin film battery on a more exposed T-shirt or backpack and then recharge your phone in other ways (but the company does not say more about how it does this), or directly The transparent battery into the phone design.
Yuhang Liu, a scientist at the Federal Institute of Technology in Lausanne, Switzerland, was impressed with the application by noting that plastic panels could also be incorporated into home curtains to power small appliances such as lamps or air cleaners. In addition to small appliances, the team also planned Use this battery to drive only a small amount of electricity sensors used to monitor the building's temperature and humidity.
The ultimate goal of Dracula Technologies is to print rectangular solar panels with 30 centimeters in length and width, and although they also admit that it will take months to develop a full smart phone panel, researchers are looking to shorten the solar energy Battery charging method of time, they believe this technology can be applied in the real world.
