"solar ink" printed paper batteries, portable
Massachusetts Institute of Technology (MIT) research team recently overthrew people's thinking about the battery They make solar cells in the form of "ink", which can be immediately generated by printing on ordinary paper. MIT pointed out that this technology is cheap and simple, and can be printed through printers. "It's easier to do than to photograph."
traditional solar panels are made to expose substrates to corrosion and high temperatures, but the new "solar ink" requires only steam, and a temperature below 120 degrees centigrade to be directly transferred to different materials, such as paper, cloth and plastic. Karen Gleason, vice president of MIT Engineering Research Institute, said that the price of paper is 1000 times cheaper than that of glass substrates in the past. And the application is higher.
experiments show that the paper battery made of "solar ink" has high durability and can be folded repeatedly, and the power generation efficiency is basically no loss. In addition, portable paper batteries are more portable and can be folded into pockets and used for power generation in the sun. The current study of the paper battery solar energy conversion rate less than 2%, can only provide electronic alarm clock and other small quantity of electricity supplies, in the next two years, researchers are expected to be able to increase the conversion rate to 8%, this is the mobile phone, iPad low power electronic devices will be available.
