Molecular Solar Ltd., a spinout company from the UK's University of Warwick, has have achieved a record voltage for organic photovoltaic cells - which means these highly flexible, low-cost solar cells can now be devolved for commercial uses in a wide range of consumer electronics.
The company’s most recent advance in the development of its organic photovoltaic (OPV) cell technology is the realization of cells with open-circuit voltages in excess of 4 volts for the first time. Molecular Solar’s research team believe this is a record for an OPV device.
“We are now very close to having highly flexible organic photovoltaic cells that will be capable of delivering electrical energy at a voltage suitable for recharging lithium ion batteries that are widely used in portable consumer electronics. Remarkably, this high voltage is achieved using a cell with only 4 junctions (sub-cells)," said Dr Ross Hatton, Research Director of the company.
“The first generation of organic photovoltaics will be exceptionally well matched to consumer electronics applications. The advantage of Molecular Solar’s high voltage cells is that a single cell can be used with no requirement to connect multiple cells in series for these applications, saving manufacturing cost," added University of Warwick researcher Professor Tim Jones, who is Chief Technology Officer of Molecular Solar.
Molecular Solar are currently finalizing an investment round to complete the up-scaling of their OPV and MS-Flexifilm™ electrode technology.
