The company’s most recent advance in the development of its organic photovoltaic (OPV) cell technology is the realisation of cells with open-circuit voltages in excess of four volts for the first time. Molecular Solar’s research team believes this is a record for an OPV device.

Dr Ross Hatton, Research Director of Molecular Solar commented:  “This is an important advance. 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)’’.  

University of Warwick researcher Professor Tim Jones, who is Chief Technology Officer of Molecular Solar, added: “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. ’’

Andrew Oldfield, Head of Cleantech at Mercia Fund Management, said: “We were attracted to Molecular Solar’s unique approach to realizing truly flexible, environmentally sustainable photovoltaics that are well matched to the burgeoning portable consumer electronics market.”

Molecular Solar are currently finalising a £5m investment round to complete the up-scaling of their OPV and MS-Flexifilm electrode technology.
