A ruthenium complex is being used in the development of a new organic semiconductor device which could revolutionise the use of solar technology.

New research from Cornell University in the US has enabled the development of a new device which shows electroluminescence and acts as a photovoltaic cell.

According to PhysOrg.com, the organic semiconductors could be used to create displays on items as thin as cloth or paper, allowing for a parasol, for example, to collect solar energy to run a portable television.

The new device is the first to use an "ionic junction", providing the thin organic semiconductor with improved performance, thereby making the technology more viable.

"Flexible means low-cost fabrication," explains George Malliaras, Cornell associate professor of materials science and engineering.

A ruthenium complex containing negative ions is used as part of the ionic junction between the two organic semiconductors.
