Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just some of the technologies that could benefit from their new discovery, which deals with “double-doped” polymers.   The majority of everyday electronics are based on inorganic semiconductors, such as silicon. Crucial to their function is a process called doping, which involves w...
