Researchers discovered when aluminum is added to the core of liquid gallium at room temperatures, nano-sheets of aluminum oxide are quickly produced at the surface of the gallium. The aluminium oxide nano-sheets are […]

Gallium [Ga], for instance, which is used in semi-conductors, including light emitting diodes [LED], photovoltaic [PV] cells, and transistors, currently has a global demand of about 200 tons. Clearly, recovering gallium is economically important. […]

To reduce even more the costs, these solar cells are build with an inexpensive ink-based process.
