Solar panels and lighting displays may soon be produced from devices virtually indistinguishable from inkjet printers, scientists predicted at the recent consumer electronics trade show (IFA) in Berlin.
The technology in question moves away from conventional electronics manufacturing, instead producing solar cells and LEDs using small organic molecules that absorb or emit light. In a solar cell, these molecules absorb light and then generate an electric charge, which is then transformed into an electric current. In an LED, the molecules respond to an electric current by emitting light of a specific color.
Organic solar cells and LEDs are significantly easier and cheaper to manufacture than conventional electronics, because films of molecules are significantly smaller and easier to work with than silicon cells. This means that not only are production costs significantly lower, but the final product is thinner, lighter and more flexible than a conventional solar cell or LED.
