Sunny side up for Warwick researchers

Researchers in the University of Warwick have announced a breakthrough in solar cell technology development.

Molecular Solar, a spinout company from the University, is developing third-generation solar cells which could be potentially used to recharge batteries for mobile electronics (such as the Kindle, mobile phones and laptops) on-the-go and even indoors. These third-generation organic solar photovoltaic cells can handle in excess of 4 volts for the first time.

Executive Chairman of Molecular Solar, Dr Ederyn Williams, said the new solar cells are based on “thin layers of organic dyes on plastic film” and “will be very light, flexible and cheap compared to existing cells made of silicon”. Dr Williams added, “the high voltage output is another potential advantage.” The cells also use non-toxic components, unlike second-generation cells.

University of Warwick researcher Professor Tim Jones, who is Chief Technology Officer of Molecular Solar, said the solar cells “will be exceptionally well-matched to consumer electronics applications” and the technology means there will be savings in manufacturing costs. However, the solar cells will take at least three years to come to market, according to Dr Williams.

The company developed out of the University of Warwick’s Chemistry Department in 2008, and has since secured more than £1m in funding to develop the product. They are currently trying to raise a further £5m to continue development and get the product to market.

The product has also been shortlisted in the Innovation in Development category in the Lord Stafford Awards, which recognise, showcase and celebrate the best in collaboration between business and academia across the Midlands.

Lord Stafford, Patron of the Awards, said: “This is another excellent example of the work done at Warwick and I wish them the very best for the awards night.” The winners will be announced on 17 November.
