Carbon electrodes could slash cost of solar panels

Max Planck researchers have found that transparent electrodes created from graphene could make solar cells and LCDs without depleting indium resources.

Experts calculate that there is only 10 years’ worth of indium left on the planet, with LCD panels consuming the majority of existing stocks.

The Max Planck team has produced electrodes just 10 graphene layers thick, or roughly five nanometers. These have a transparency of about 80 percent, which is comparable to the indium-based electrodes used in dye-sensitized solar cells.
