Scientists in Australia have lit the path towards replacing wires in electrochemical devices by using visible light to create electrical currents on a stabilised silicon semiconductor electrode.
Electrodes in conventional devices must be connected to an external electrical circuit, often requiring a mesh of wires and bonding pads to produce an array of independently controlled electrodes. These components take up a vast amount of space on electronic chips, limiting the electrode density. Read the full article in Chemistry World»
